Published: June 2014

This study aimed to manipulate the texture and elemental composition of the novel sheaths produced by the iron-oxidizing bacterium Leptothrix in culture by altering components of the medium. When previously isolated strain OUMS1 was cultured in media (pH 7.0 throughout incubation) containing various levels of Si on a rotary shaker at 20 °C and 70 rpm for 14 days, the strain was able to reproduce in media with up to 300 ppm Si, and the hollow microtubular architecture of the sheath was maintained even at 300 ppm Si. The constitutional iron oxide phase changed from poorly crystalline lepidocrocite at 0 ppm Si to X-ray diffraction (XRD)-amorphous 2-line ferrihydrite at 100–300 ppm via their mixture phase with intermediate Si content (Si-30 and -50 ppm). The results strongly indicate that the chemical character and crystallinity of the sheath texture can be regulated by culture conditions, especially components of the medium.

Published: June 2014

Headspace-solid phase microextraction-gas chromatography-mass spectrometry (HS-SPME-GC-MS) was used to identify the volatile organic compounds (VOCs) of the different flower development stages of Cananga odorata for the evaluation of floral volatile polymorphism as a basis to determine the best time of harvest. Electronic nose results, coupled with discriminant factor analysis, suggested that emitted odors varied in different C. odorata flower development stages, including the bud, display-petal, initial-flowering, full-flowering, end-flowering, wilted-flower, and dried flower stages. The first two discriminant factors explained 97.52% of total system variance. Ninety-two compounds were detected over the flower life, and the mean Bray–Curtis similarity value was 52.45% among different flower development stages. A high level of volatile polymorphism was observed during flower development. The VOCs were largely grouped as hydrocarbons, esters, alcohols, aldehydes, phenols, acids, ketones, and ethers, and the main compound was β-caryophyllene (15.05%–33.30%). Other identified compounds were β-cubebene, D-germacrene, benzyl benzoate, and α-cubebene. Moreover, large numbers of VOCs were detected at intermediate times of flower development, and more hydrocarbons, esters, and alcohols were identified in the full-flowering stage. The full-flowering stage may be the most suitable period for C. odorata flower harvest.

Published: June 2014

Antrodia cinnamomea (AC) has been widely used as a folk medicine in the prevention and treatment of liver diseases, such as hepatitis, hepatic fibrosis, and hepatocellular carcinoma. Previous studies have indicated that triterpenoids and benzenoids show selective cytotoxicity against human hepatoma cell lines. The aim of the study was to compare the triterpenoid content of extract and the extract-induced cytotoxicity in HepG2 cells from mycelia extracts of solid state cultured AC obtained by supercritical fluid extraction (SFE) and the conventional solvent extraction method. SFE with CO2 mixed with a constant amount of ethanol co-solvent (10% of CO2 volume) applied at different temperatures and pressures (40, 60 and 80 °C and, 20.7, 27.6 and 34.5 Mpa) was also compared in the study. Although the extraction yield of triterpenoids (59.7 mg/g) under the optimal extraction conditions of 34.5 MPa (5000 psi)/60 °C (designated as sample S-5000-60) was equivalent to the extraction yield using conventional liquid solvent extraction with ethanol (ETOH-E) at room temperature (60.33 mg/g), the cytotoxicity of the former against the proliferation of HepG2 cell line measured as the inhibition of 50% of cell growth activity (IC50) at dosages of 116.15, 57.82 and 43.96 µg/mL was superior to that of EtOH-E at 131.09, 80.04 and 48.30 µg/mL at 24, 48 and 72 h, respectively. Additionally, we further proved that the apoptotic effect of S-5000-60 presented a higher apoptosis ratio (21.5%) than ETOH-E (10.5%) according to annexin V-FITC and propidium iodide double staining assay results. The high affinity and selectivity of SFE on bioactive components resulted in a higher extraction efficiency than conventional solvent extraction. The chemical profile of the obtained extracts from solid state cultivated mycelium of AC was also determined by high-performance liquid chromatography electrospray ionization tandem mass spectrometry (LC-MS/MS), whereby three benzenoids and four triterpenoids were found for the first time in SFE extracts with 4,7-dimethoxy-5-methyl-l,3-benzodioxole (5.78 mg/g) being the most abundant component, followed by 2,4-dimethoxy-6-methylbenzene-1,3-diol (3.03 mg/g) and dehydroeburicoic acid (0.40 mg/g).

Published: June 2014

The main objective of this research was to determine the effects of a long-term ketogenic diet, rich in polyunsaturated fatty acids, on aerobic performance and exercise metabolism in off-road cyclists. Additionally, the effects of this diet on body mass and body composition were evaluated, as well as those that occurred in the lipid and lipoprotein profiles due to the dietary intervention. The research material included eight male subjects, aged 28.3 ± 3.9 years, with at least five years of training experience that competed in off-road cycling. Each cyclist performed a continuous exercise protocol on a cycloergometer with varied intensity, after a mixed and ketogenic diet in a crossover design. The ketogenic diet stimulated favorable changes in body mass and body composition, as well as in the lipid and lipoprotein profiles. Important findings of the present study include a significant increase in the relative values of maximal oxygen uptake (VO2max) and oxygen uptake at lactate threshold (VO2 LT) after the ketogenic diet, which can be explained by reductions in body mass and fat mass and/or the greater oxygen uptake necessary to obtain the same energy yield as on a mixed diet, due to increased fat oxidation or by enhanced sympathetic activation. The max work load and the work load at lactate threshold were significantly higher after the mixed diet. The values of the respiratory exchange ratio (RER) were significantly lower at rest and during particular stages of the exercise protocol following the ketogenic diet. The heart rate (HR) and oxygen uptake were significantly higher at rest and during the first three stages of exercise after the ketogenic diet, while the reverse was true during the last stage of the exercise protocol conducted with maximal intensity. Creatine kinase (CK) and lactate dehydrogenase (LDH) activity were significantly lower at rest and during particular stages of the 105-min exercise protocol following the low carbohydrate ketogenic diet. The alterations in insulin and cortisol concentrations due to the dietary intervention confirm the concept that the glucostatic mechanism controls the hormonal and metabolic responses to exercise.

Published: June 2014

Contemporary satellite Earth Observation systems provide growing amounts of very high spatial resolution data that can be used in various applications. An increasing number of sensors make it possible to monitor selected areas in great detail. However, in order to handle the volume of data, a high level of automation is required. The semi-automatic change detection methodology described in this paper was developed to annually update land cover maps prepared in the context of the Geoland2. The proposed algorithm was tailored to work with different very high spatial resolution images acquired over different European landscapes. The methodology is a fusion of various change detection methods ranging from: (1) layer arithmetic; (2) vegetation indices (NDVI) differentiating; (3) texture calculation; and methods based on (4) canonical correlation analysis (multivariate alteration detection (MAD)). User intervention during the production of the change map is limited to the selection of the input data, the size of initial segments and the threshold for texture classification (optionally). To achieve a high level of automation, statistical thresholds were applied in most of the processing steps. Tests showed an overall change recognition accuracy of 89%, and the change type classification methodology can accurately classify transitions between classes.
Sensitivity Comparison of Vapor Trace Detection of Explosives Based on Chemo-Mechanical Sensing with Optical Detection and Capacitive Sensing with Electronic Detection

Published: June 2014

The article offers a comparison of the sensitivities for vapour trace detection of Trinitrotoluene (TNT) explosives of two different sensor systems: a chemo-mechanical sensor based on chemically modified Atomic Force Microscope (AFM) cantilevers based on Micro Electro Mechanical System (MEMS) technology with optical detection (CMO), and a miniature system based on capacitive detection of chemically functionalized planar capacitors with interdigitated electrodes with a comb-like structure with electronic detection (CE). In both cases (either CMO or CE), the sensor surfaces are chemically functionalized with a layer of APhS (trimethoxyphenylsilane) molecules, which give the strongest sensor response for TNT. The construction and calibration of a vapour generator is also presented. The measurements of the sensor response to TNT are performed under equal conditions for both systems, and the results show that CE system with ultrasensitive electronics is far superior to optical detection using MEMS. Using CMO system, we can detect 300 molecules of TNT in 10+12 molecules of N2 carrier gas, whereas the CE system can detect three molecules of TNT in 10+12 molecules of carrier N2.
Orientation Measurement Based on Magnetic Inductance by the Extended Distributed Multi-Pole Model
Authors: Wu Fang , Moon Seung , Son Hungsun
Published: June 2014

This paper presents a novel method to calculate magnetic inductance with a fast-computing magnetic field model referred to as the extended distributed multi-pole (eDMP) model. The concept of mutual inductance has been widely applied for position/orientation tracking systems and applications, yet it is still challenging due to the high demands in robust modeling and efficient computation in real-time applications. Recently, numerical methods have been utilized in design and analysis of magnetic fields, but this often requires heavy computation and its accuracy relies on geometric modeling and meshing that limit its usage. On the other hand, an analytical method provides simple and fast-computing solutions but is also flawed due to its difficulties in handling realistic and complex geometries such as complicated designs and boundary conditions, etc. In this paper, the extended distributed multi-pole model (eDMP) is developed to characterize a time-varying magnetic field based on an existing DMP model analyzing static magnetic fields. The method has been further exploited to compute the mutual inductance between coils at arbitrary locations and orientations. Simulation and experimental results of various configurations of the coils are presented. Comparison with the previously published data shows not only good performance in accuracy, but also effectiveness in computation.
Parental Background and Union Formation Behavior of Native Born Individuals in Sweden with a Foreign Background
Authors: Çelikaksoy Aycan
Published: June 2014

Social cohesion in destination countries is an increasingly important issue due to the multiethnic structures in these countries and due to ongoing international migration. Union formation of individuals across different backgrounds can be seen as an indicator of social cohesion. However, this phenomenon is important not only in the case of first generation migrants but also for their descendants. Thus, this paper analyzes the determinants of intergroup union formation patterns of the native born individuals with a foreign background focusing on the role of parental background in addition to individual as well as marriage market characteristics. High quality data at the individual level, from Statistics Sweden, for the whole population of interest is utilized. The results indicate that parental composition is an important determinant of union formation behavior. Furthermore, there are gender specific pathways of the parental background effects.

Abstract. - If the part played by means of conveyance in economics is studied from a geographical standpoint, considering the organizing role of transports through lands, the ecological consequences upon the environment have very seldom been dealt with by geographers. Yet many reasons are in favour of the introduction of ecological considerations in the geographical study of transports. From the only standpoint of the importance of transport areas, the surface taken up in France is a little more than one per cent of the country, for the main routes only, the relastionship between the economic help and the surface taken up showing obvious differences between the different means of communication.

Résumé. - L'équipe de Géomorphologie historique et climatique a été créée en 1977, dans le cadre de la restructuration du Laboratoire de Géographie physique. Elle a choisi comme thème de recherche majeur celui de l'évolution des paysages de la rive nord-méditerranéenne depuis 15 000 ans. Ce thème correspond à un «créneau» jusqu'à ce jour peu occupé, entre la dernière période froide et le dernier millénaire, objet, actuellement, de recherches intensives. Elle s'efforce de promouvoir une recherche pluridisciplinaire, dont ce colloque est le reflet par la présence d'historiens, palynologues, physiciens, pédologues... Elle a pour objectifs d'éclairer les relations qui se tissent entre les divers éléments du paysage- système, de reconstituer l'évolution de ce dernier au cours du temps, enfin de proposer une méthode et des modèles d'intervention aux responsables de la gestion du milieu méditerranéen (Programme M.A.B. de /'Unesco, par exemple). - Le modèle proposé ensuite (3e) décrit les modalités de l'intervention du facteur climatique. Les études de terrain visent à établir une chronologie et à isoler la marque du climat dans toute une gamme de documents.

MCDM APPROACH TO EVALUATING BANK LOAN DEFAULT MODELS
Authors: Kou Gang , Peng Yi , Lu Chen
Published: June 2014

Banks and financial institutions rely on loan default prediction models in credit risk management. An important yet challenging task in developing and applying default classification models is model evaluation and selection. This study proposes an evaluation approach for bank loan default classification models based on multiple criteria decision making (MCDM) methods. A large real-life Chinese bank loan dataset is used to validate the proposed approach. Specifically, a set of performance metrics is utilized to measure a selection of statistical and machine-learning default models. The technique for order preference by similarity to ideal solution (TOPSIS), a MCDM method, takes the performances of default classification models on multiple performance metrics as inputs to generate a ranking of default risk models. In addition, feature selection and sampling techniques are applied to the data pre-processing step to handle high dimensionality and class unbalancedness of bank loan default data. The results show that K-Nearest Neighbor algorithm has a good potential in bank loan default prediction.
CRITICALITY ASSESSMENT OF ENERGY INFRASTRUCTURE

Published: June 2014

After the last major accidents in the energy sector of the last decade (USA and Canada (2003), India (2012), Russian-Ukrainian (2009)), energy infrastructure criticality assessment has become one of the most important issues. It has become the topical subject of the economy and national security in all countries. There is no single measure unit for the assessment of critical infrastructure with respect to “interdependency” among critical infrastructure sectors. This paper proposes to use criticality of infrastructure element as a measure to assess the importance of considered element to the normal activity of all sectors of infrastructure. The pilot numerical simulation of heat and electricity infrastructure was performed to demonstrate the implementation of the application of developed method for the assessment of infrastructure functionality and criticality.
HOW DOES CREDIT PORTFOLIO DIVERSIFICATION AFFECT BANKS’ RETURN AND RISK? EVIDENCE FROM CHINESE LISTED COMMERCIAL BANKS
Authors: Chen Yibing , Shi Yong , Wei Xianhua , Zhang Lingling
Published: June 2014

Does diversification of credit portfolio indeed lead to increased performance and reduced risk of banks as traditional portfolio theory suggests? This paper investigates empirically the effects of diversification on the Chinese banks’ return and risk from the aspect of sector. Panel data on 16 Chinese listed commercial banks during the 2007–2011 period is used for the study. We construct a new diversification measure, taking systematic risk of different sectors into consideration by weighting them with their betas and compare the results with those of more conventional measure HHI. We find that sectorial diversification is associated with reduced return and also decreased risk at the same time, which however, contradicts existing findings in developed countries such as Italy and Germany, and also in emerging economies such as Brazil and Argentina. Our analysis also provides important implication for regulators and policy makers of the banks in emerging markets.

Published: June 2014

La prise en charge des auteurs de violences sexuelles par des structures de soins intégrés aux lieux de détention a inspiré la mise en place de peines dites « de suivi socio-judiciaire » se déroulant après l’incarcération, hors des murs de la prison. Mais cette transposition ne va pas de soi, elle confronte le dispositif public de soin psychiatrique français à un nouveau type de pratique qui modifie profondément les repères établis, suscitant des résistances et un réaménagement des pratiques. Cet article propose de relever plusieurs de ces difficultés et d’en saisir les effets sur les pratiques psychothérapiques d’inspiration psychanalytique à travers les notions de rencontre clinique et d’objet de relation.

La question du suicide, le pari de la rencontre : quelques dispositifs de prévention autour du mouvement suicidaire chez l'adolescent
Authors: Edan Anne , Schmid Nichols Nathalie
Published: June 2014

Le suicide est la première cause de mortalité en Suisse chez les 15-24 ans. La rencontre avec un adolescent pris dans un mouvement suicidaire est un moment clé. Les auteurs développent le pari de cette rencontre pour aborder la question tendue par l’intention suicidaire de l’adolescent. De cette rencontre, l’Unité de crise (HUG-Fondation Children Action) pour adolescents de Genève va proposer un soin sur mesure. S’intéressant aux pré-requis de la demande d’aide et aux dispositifs de répondance en présence ou à distance actuellement offerts au sein du volet « prévention » de l’Unité, les auteurs considèrent que ces différentes modalités ne peuvent se substituer les unes aux autres, mais qu’il est essentiel de les conjuguer pour qu’une rencontre puisse avoir lieu.

Managing Dementia Symptoms and Needs Using Technology
Authors: Kerssens Chantal , Sattler Melany , Monteiro Alisha
Published: June 2014

Dementia is a difficult and costly disease to manage. Although caregivers and patients have indicated they need support for activities of daily living and debilitating neuropsychological symptoms, most technology innovations focus on safety and social contact. This feasibility study tested a care technology designed to manage dementia symptoms and everyday routines using common, nonpharmacological interventions. It was implemented in two formal care environments (memory care, assisted living). In Sample 1, independent observers decided which symptoms were present or absent in individual residents pre-intervention and 1 and 2 months during the intervention. In Sample 2, independent observers determined the desired status (goals) for individual residents prior to intervention and evaluated resident status 1 and 2 months into the intervention. The intervention was associated with a reduction in symptoms and progression toward wellness goals, suggesting that nondrug interventions for managing symptoms and daily routines in dementia can be delivered effectively using advanced technology.

Eighty Percent by 2020: The Present and Future of RN-to-BSN Education
Authors: McEwen Melanie , Pullis Bridgette R. , White Mary Joe , Krawtz Susan
Published: June 2014

More than 600 RN-to-BSN programs currently exist in the United States, and the numbers of programs and students are growing rapidly. This unprecedented growth is a result of several factors, including the Institute of Medicine’s recommendation that 80% of RNs be BSN prepared by 2020. This survey was undertaken to explore key ideas and issues related to RN-to-BSN education to gather information on how RN-to-BSN programs are changing and to uncover concerns posited by program directors. The survey indicated that lack of standardization has resulted in significant variability in expectations and requirements among RN-to-BSN programs. Further, numerous questions need to be answered and concerns addressed to develop strategies to maintain growth, improve access, and remove barriers without sacrificing quality. Findings can be used to ensure that RN-to-BSN education prepares graduates for the future health care system and that the outcome is not just a piece of paper. [

Published: June 2014

The wide disparities in health by race and ethnicity across the nation underscore the continuing need to increase the number of racial and ethnic minorities in the nursing workforce. In their roles as educators and researchers, minority nursing faculty help to alleviate the current disconnect between health care providers and the population that nurses serve. The authors have developed a program to increase the number of minority students in the baccalaureate nursing program at their university and to prepare them to enroll in doctoral programs within 1 year of graduation. The Careers Beyond the Bedside program offers undergraduates preentry, academic enrichment, and graduate school preparation activities designed to facilitate careers as nursing faculty educators and researchers.

Improvement in Critical Thinking Dispositions of Undergraduate Nursing Students Through Problem-Based Learning: A Crossover-Experimental Study
Authors: Yu Dehong , Zhang Yaqing , Xu Yun , Wu Juemin , Wang Caifeng
Published: June 2014

Critical thinking (CT) is important to nursing education and practice. Although there is evidence that active learning approaches, such as problem-based learning (PBL), are effective in developing CT dispositions, the findings are inconclusive. This study examines the effect of PBL on the development of CT dispositions in nursing students using a crossover-experimental study in a course offered to nursing students in China. All students were randomly assigned to two parallel groups, with one group receiving PBL and the other receiving lecture-based learning (LBL) as a control. The CT Dispositions Inventory-Chinese Version was administered before and after the semester-long course. Data were collected at three time points. No significant differences between groups were noted in overall and sub-scale scores at baseline; however, pronounced differences in overall posttest scores existed between the PBL and LBL groups. Thus, PBL learning significantly enhanced the CT dispositions of nursing students enrolled in Medical–Surgical Nursing II. [

Preparing for Patient-Centered Care: Assessing Nursing Student Knowledge, Comfort, and Cultural Competence Toward the Latino Population
Authors: Mayo Rachel M. , Sherrill Windsor W. , Truong Khoa D. , Nichols Christina M.
Published: June 2014

As the Latino population continues to grow throughout the United States, cultural competence training of nursing students at the baccalaureate level has become a priority. This study aimed to explore undergraduate nursing students’ attitudes and beliefs toward Latino patients and their perceived readiness to provide care to Latino patients. A cross-sectional survey was conducted at four major nursing schools in the southeastern United States, which is the region that has seen the highest percentage of growth in the Latino population. Results from multivariable regression suggest that social interaction with Latino individuals and cultural immersion in a Spanish-speaking country predict student knowledge, cultural competence, and comfort with Latino patients. Direct influence by nursing programs, such as clinical experience, coursework, and language proficiency, are positively associated with the designed outcomes, but these relationships are not statistically significant. Our findings suggest that dosage of training matters. Implications for student recruitment, selection, and training are discussed. [

Authors: Ziebarth Noël M. , Lorenzo Michael A. , Chow Jessica , Cabot Florence , Spooner Gregory J. R. , Dishler Jon , Hjortdal Jesper Ø. , Yoo Sonia H.
Published: June 2014

PURPOSE:

To assess the cut quality of the anterior and posterior surfaces of intrastromal refractive lenticules removed during small incision lenticule extraction (SMILE).

METHODS:

The VisuMax femtosecond laser (500 kHz; Carl Zeiss Meditec, Dublin, CA) was used to perform SMILE on 8 eyes of 5 individuals to correct only myopia (no cylinder). The cut energy index was 26 (equivalent to an energy of 130 nJ) with a 2.5 × 2.5
μ
m spot/track separation. The lenticule diameter was 6.5 mm with a minimum edge thickness of 15
μ
m and the cap diameter was 7.3 mm with an intended thickness of 120
μ
m. After laser treatment, the lenticule was loosened with a spatula and removed with forceps. The extracted lenticules were placed in 2% formalin and sent for imaging with an environmental scanning electron microscope. Images of the anterior and posterior surfaces of the lenticules were obtained at multiple magnifications (100×, 250×, and 500×). Surface quality was evaluated by an investigator who specializes in electron microscopy using three criteria: overall surface regularity, percent of surface irregularity, and position of irregular area.

RESULTS:

Both the anterior and posterior surfaces of the extracted lenticules were smooth and absent of surface irregularities. The cut edges also appeared uniform. Jagged edges were seen in several images, but were clearly caused by the forceps during extraction.

CONCLUSIONS:

Using the VisuMax laser to perform SMILE produces smooth cuts absent of surface irregularities.

Dynamic Scheimpflug-based Assessment of Keratoconus and the Effects of Corneal Cross-linking
Authors: Bak-Nielsen Sashia , Pedersen Iben B. , Ivarsen Anders , Hjortdal Jesper
Published: June 2014

PURPOSE:

To evaluate the ability of the Corvis ST (Oculus Optikgeräte GmbH, Wetzlar, Germany) to distinguish between normal and keratoconic corneas and detect the possible stiffening effect of corneal cross-linking (CXL) in vivo.

METHOD:

A retrospective study including 86 eyes of 86 participants (27 patients with untreated keratoconus, 27 patients with CXL-treated keratoconus, and 32 normal patients). The prospective study included 9 keratoconic eyes measured 24 days before and 97 days after CXL.

RESULTS:

The following parameters from the Corvis ST showed a significant difference between keratoconic and normal eyes: intraocular pressure, corneal thickness, first applanation time, highest concavity (HC) radius, HC deformation amplitude, and HC deflection amplitude (analysis of variance,
P
< .0001). Receiver operating characteristic curve analysis showed the highest area under the curve for HC deflection amplitude (0.942,
P
< .0001). Prediction intervals for individual measurements within the two groups overlapped considerably. No significant difference was found between the untreated and CXL-treated keratoconus groups (analysis of variance,
P
> .05). Measurements performed before and after CXL in the same patients showed significant difference in HC deformation amplitude (
P
= .018), HC time (
P
= .018), and second applanation time (
P
= .027).

CONCLUSIONS:

Although the corneal deformation characteristics differed between groups of keratoconic and normal eyes, this study showed that the standard parameters of the Corvis ST cannot readily be used for diagnosis of keratoconus in the individual patient or to document the effect of CXL in vivo.

Hypertensive Choroidopathy in Pre-eclampsia: Two Consecutive Cases
Authors: Dewilde Evelien , Huygens Marc , Cools Geertrui , Van Calster Joachim
Published: June 2014

Hypertensive retinopathy is well known, but choroidopathy is uncommon and associated with acute increases in blood pressure. Nonperfused areas of the choriocapillaris lead to changes of overlying retinal pigment epithelium (RPE), resulting in neurosensory or RPE detachments. The authors describe two patients with serous retinal detachments associated with acute arterial hypertension in pre-eclampsia and HELLP (hemolysis, elevated liver enzyme levels, and low platelet count) syndrome. Subretinal fluid was demonstrated on ultra-widefield fundus imaging and optical coherence tomography. Fluorescein angiography and indocyanine green angiography enabled imaging of the choroidal hypoperfusion. All signs and symptoms resolved after 1 and 3 months, respectively, with persistent macular pigmentary changes in both patients.

Pars Plana Vitrectomy for Macular Schisis Associated With Peripapillary Intrachoroidal Cavitation
Authors: Yoshizawa Chikako , Saito Wataru , Noda Kousuke , Ishida Susumu
Published: June 2014

A case of retinoschisis associated with peripapillary intrachoroidal cavitation (ICC) was successfully treated with pars plana vitrectomy. A 70-year-old woman developed macular elevation and peripapillary ICC in her right eye. Optical coherence tomography revealed retinoschisis with retinal detachment in the macula. A microhole was observed within the myopic conus. A narrow passage was observed linking the ICC with the schisis cavity, complicated by a peripapillary epiretinal membrane tissue adjacent to the passage. The patient underwent vitrectomy with removal of the membrane tissue. Complete regression of the retinoschisis was observed, with closure of the connection channel between the ICC and schisis cavity. These findings suggest that the communication channel between the vitreous and schisis cavities was formed due to the traction exerted by the membrane tissue on the ICC that had generated a connecting path to the schisis cavity.

High-speed Cannula Detachment Into the Eye During Hydrodissection
Authors: McPherson Zachary E. , Lau Oliver C.F. , Chen Tony S. , Kam Andrew W. , Amjadi Shahriar , Zhang Michael G. , Playfair T. Justin , Agar Ashish , Francis Ian C.
Published: June 2014

Detachment of a hydrodissection cannula during a phacoemulsification procedure appeared to produce no adverse sequelae during surgery. Day 1 postoperatively, two nonpenetrating hemorrhagic retinal lesions were identified; there was no evidence of posterior capsular perforation. Day 6 postoperatively, the pupil was temporally peaked by a fine vitreous strand running to the main-port incision in the superotemporal cornea. This was divided with Nd:YAG laser, and argon laser was applied to encircle the two retinal lesions. Postoperative uncorrected visual acuity remained 6/4 at day 1, day 6, and week 4 (3 weeks after laser application) follow-up visits. Surgeons must accept responsibility for confirming the integrity of the cannula and syringe connection before beginning hydrodissection, which can be highly destructive to intracameral structures.
