Authors: Kim Gwangjun , Park Min Young , Han Seung Su 
Published: March 2014

Abstract
Radiofrequency ablation (RFA) has become widely accepted as first-line management for twin reversed arterial perfusion (TRAP) sequence. Most RFA procedures have been performed using RFA needles of 14–17 gauge (G) focusing on an acardiac mass at an average age of 21 weeks of gestation (17–24 weeks). In this case report, we describe treatment of TRAP sequence using RFA with a 20 G needle focusing a feeding artery on the placental surface at gestational age of 11+6.
Therapeutical Approach of Osteoporosis — a Multidisciplinary Issue
Authors: Camelia Gliga , Simona Marcu , M Gliga 
Published: March 2014

AbstractOsteoporosis is the most frequent systemic disease of the bone, that affects elderly, mainly women in menopause. It can be defined by lowering of bone mass and microarchitectural deterioration of the bone tissue, resulting in an increased bone fragility. Main complications of osteoporosis are fractures of the vertebrae, hips and forearm. In view of its large variety of causes and manifestations, diagnostic and therapeutical approach in osteoporosis represents a multidisciplinary issue. The accurate diagnosis of osteoporosis is based on a method that measures the bone mineral density, expressed by the T-score, using dual energy X-ray absorptiometry, so called DXA. Lately, in practice in order for establishing the risk of osteoporosis and osteoporotic fracture the FRAX tool is increasingly used (The Fracture Risk Assessment). Treatment of osteoporosis is complex involving non-pharmacological and pharmacological measures. Non-pharmacological methods include preventive measures like exercise, external hip protectors, increase of dietary intake of calcium, vitamin D and proteins, especially in elderly, over 65 years. Pharmacological measures are represented by different types of drugs, including biphosphonates, bone formation stimulatory drugs, agents with new mechanisms of action, hormone replacement therapy and they will be indicated only after a detailed clinical and paraclinical examination of the patient. Regardless of the chosen pharmacological measure, periodical follow-up of efficacy, side-effects and complications of antiosteoporotic treatment, by clinical examination and laboratory investigations targeting bone remodelling, is strongly indicated.

Published: March 2014

Abstract Introduction: Coronary calcium score, as determined by Angio CT multislice, has been proved to represent a reliable parameter which reflects the global cardiovascular risk. We aimed to study the characteristics of culprit lesions in Acute Coronary Syndrome (ACS) patients with low versus high calcium score. Material and methods: A total of 45 patients with ACS underwent 64-slice CCTA. Group 1 - 19 patients with Ca score below 400HU, Group 2 - 26 patients with calcium score >400HU. In all patients a complex CT analysis of the culprit plaque was performed. Results: There were no significant differences between the groups at baseline as regard to age, gender, cardiovascular risk factors (p>0.2). In patients with high calcium score, culprit lesions presented a significantly larger amount of plaque burden than in patients with low calcium score (82.8ml versus 131.81ml, p <0.0001). This was also true when assessing in a subanalysis different cut-off points for definition of relatively higher calcium score (89.66ml versus 137.93ml, p <0.0001, for calcium score cut off 600HU, 97.88ml versus 137.57ml, p<0.0001 for calcium score cut-off of 1000HU). Conclusion: Our data shows that patients with high calcium score who develop an acute coronary syndrome present larger atheromatous plaque than those with low calcium scores, and theseverity of the culprit lesions correlates with global cardiovascular risk as expressed by a high calcium score
Anastomotic Leaks after Colorectal Surgery: a Prognostic Score
Authors: Alexandra Caziuc , A Mironiuc 
Published: March 2014

Abstract
Introduction: Anastomotic leaks are one of the most dreaded complications in colorectal surgery. At the ground of this problem remain the nefarious prognostic over the patient’s life, the difficulties in early diagnosis and the optimal choice of therapeutical methods. The goal of our research was to evaluate the significance of possible risk factors in the postoperative evolution of patients following colorectal interventions and to design a prognostic score. Material and methods: We performed a retrospective study on 298 cases of patients with inflammatory, neoplastic or traumatic lesions for which there was chosen a digestive anastomosis including the colon. The presumed risk factors in our analysis were: age, comorbidity evaluated by Charlson Score, etiology, toxics, use of nonsteroidal anti-inflammatory substances or corticoids, parameters such as leucocytes, hemoglobin, urea, total seric bilirubin, glycaemia, albumins, neoadjuvant therapy, type of suture, quantity of fluids received intraoperatory. All data were analyzed using R-Commander. Results: All parameters for which we demonstrated a statistical significance (p <0.05) for an unfavorable evolution were included in a prognostic score, designed in correlation with the statistical relation between the factors. We obtained values that certified a strong association (0.75) between a high prognostic score and an increased number of anastomotic leaks. Conclusions: The practical utility of the score is mainly for the anticipation of postoperative complications. A high level score underlines that prior to surgery it is essential to balance the biochemical abnormalities and to choose properly the moment and type of surgical intervention

Published: March 2014

Abstract
Background: Treatment of esophageal and esocardial cancer in patients over 60 years involves a particular management. Considering the comorbidities specific to this category of patients, recent data from the literature indicate an increased incidence of mortality and morbidity following therapy. Material and method: We retrospectively studied a group of 55 patients admitted to the Surgical Clinic I of the County Emergency Clinical Hospital Tîrgu Mureș, in the January 1st, 2007 - December 31st, 2011 period, diagnosed with esophageal and esocardial cancer. Patients were divided into two groups: group I under the age of 60 years, and group II over this age. Inclusion criteria were age, diagnosis (tumor location), and we followed a series of parameters: demographics, type of surgery, the biological profile of patients, immediate postoperative morbidity and mortality. Results: No statistically significant differences were observed in terms of demographics: gender (p = 0.78), area of origin (p = 0.69). The number of hospitalization days (p = 0.20) was influenced by the type of surgery, as well as pre- and postoperative comorbidities. Immediate postoperative mortality was 16.56%, the differences between the two groups was not statistically significant (p = 0.58). Parameters with statistical significance were found to be: age (p <0.0001), tumor location, type of surgery (p = 0.0031) and radical versus palliative surgery (p = 0.03). Conclusions: Therapeutic attitude in patients over 60 years should be correlated with specific particularities to this category. Selection of patients for surgery and type of surgery is dictated by the patient's condition and quantified by anesthesia and surgery team

Authors: Gmerek Artur 
Published: March 2014

Abstract
This paper deals with mechanical and hardware design of a robot, used for the rehabilitation of upper extremities. It has been called ARR-1 (Arm Rehabilitation Robot). The robot has a semi-exoskeleton structure. This means that some parts of the robot fit closely to the human arm (an orthosis), but the weight of the construction does not load patient’s body. The device is used for the whole arm rehabilitation, but active joints are only situated in glenohumeral and elbow joints. The robot is electrically actuated

Objectives: The present study was conducted aiming to investigate lipid profile in patients with subclinical hypothyroidism as compared to age and sex matched controls.Methods: The study population consisted of total 80 subjects; 40 patients (cases) and 40 controls. Serum free tri-iodothyronine (fT3) and free thyroxine (fT4) were estimated by microplate competitive enzyme immunoassay, and thyroid stimulating hormone (TSH) measured by sandwich enzyme immunoassay. Lipid profile tests: Total Cholesterol, triglycerides, high density lipoprotein (HDL) cholesterol were estimated by enzymatic methods and low density lipoprotein cholesterol (LDL) was calculated by Friedewald’s formula.Results: Significant differences were observed between lipid parameters in case Vs controls: total cholesterol (4.9±1.1 Vs 4.3±1.0 mmol/L, P=0.03), triglycerides (1.9±0.7 Vs 1.6±0.6 mmol/L, P=0.02) and LDL cholesterol levels (3.5±1.1 Vs 2.9±0.9 mmol/L, P=0.02). In case Vs controls no significant differences were observed between HDL Cholesterol (1.1±0.2 Vs 1.1±0.7 mmol/L, P=0.07), VLDL (0.9±0.4 Vs 0.8±0.3 mmol/L, P=0.1) and Cholesterol/HDL ratio (4.48±1.40 Vs 4.06±0.89, P=0.118). Elevated TSH level were found in cases Vs controls (12.42±7.08 Vs 2.69±0.20 mIU/L, P=0.01) which was statistically significant. The subjects on control group were euthyroid, however increased fT3 (3.9±0.8Vs 4.6±0.8 pmol/L, P=<0.01) and fT4 (17.1±3.9Vs 21.2±.3.7 pmol/L, P=<0.01) values were observed in controls than cases, which was statistically significant.Conclusion: The results of the present study suggest that cases of subclinical hypothyroidism are at risk of dyslipidemia as compared to controls. Large population based studies are needed to generalize these findings and establish the therapeutic guidelines for implementing lipid lowering agents in subclinical hypothyroidism.Asian Journal of Medical Science, Volume-5(3) 2014: 22-25http://dx.doi.org/10.3126/ajms.v5i3.9251
Su, X. (2011). Reflexivität im Chinesischen: Eine integrative Analyse: Mit zwei Anhängen von Hans-Heinrich Lieb. (XIV + 293 pp.). Frankfurt am Main: Peter Lang. Paperback.
Authors: PETROVČIČ Mateja 
Published: March 2014

This book was published in the Linguistics Series of European University Studies, and is written in German. As the book's title suggests, this monograph is primarily a comprehensive analysis of reflexivity in spoken Standard Chinese in the framework of Integrational Linguistics. The author demonstrates that Chinese marks reflexivity only phonologically, with the use of reflexive pronoun(s), and argues that ziji (自己) is the only reflexive pronoun in Standard Chinese.
Different languages distinguish between referential and non-referential reflexive pronouns, and the author briefly demonstrates this with German sich. Referential uses denote semantic reflexivity (inhaltliche Reflexivität), whereas non-referential uses represent formal reflexivity (formale Reflexivität). Su asserts that the Chinese reflexive pronoun ziji is always referential and that there is no formal reflexivity in Chinese.
Since the research mainly focuses on the word ziji, not only in its reflexive usage but also in relation to intensifying and contrastive meanings and effects, this monograph could also be considered as a comprehensive research on ziji in Standard Chinese.
Multiple hydrological attractors under stochastic daily forcing: 1. Can multiple attractors exist?
Authors: Peterson T. J. , Western A. W. 
Published: March 2014

AbstractIncluding positive feedbacks in hydrological models has recently been shown to result in complex behavior with multiple steady states. When a large disturbance, say a major drought, is simulated within such models the hydrology changes. Once the disturbance ends the hydrology does not return to that prior to the disturbance, but rather, persists within an alternate state. These multiple steady states (henceforth attractors) exist for a single model parameterization and cause the system to have a finite resilience to such transient disturbances. A limitation of past hydrological resilience studies is that multiple attractors have been identified using mean annual or mean monthly forcing. Considering that most hydrological fluxes are subject to significant forcing stochasticity and do not operate at such large timescales, it remains an open question whether multiple hydrological attractors can exist when a catchment is subject to stochastic daily forcing. This question is the focus of this paper and it needs to be addressed prior to searching for multiple hydrological attractors in the field. To investigate this, a previously developed semidistributed hillslope ecohydrological model was adopted which exhibited multiple steady states under average monthly climate forcing. In this paper, the ecohydrological model was used to explore if feedbacks between the vegetation and a saline water table result in two attractors existing under daily stochastic forcing. The attractors and the threshold between them (henceforth repellor) were quantified using a new limit cycle continuation technique that upscaled climate forcing from daily to monthly (model and limit cycle code is freely available). The method was used to determine the values of saturated lateral hydraulic conductivity at which multiple attractors exist. These estimates were then assessed against time‐integration estimates, which they agreed with. Overall, multiple attractors were found to exist under stochastic daily forcing. However, changing the climate forcing from monthly to daily did significantly reduce the parameter range over which two attractors existed. This suggests fewer catchments may have multiple attractors than previously considered.
Is the Dupuit assumption suitable for predicting the groundwater seepage area in hillslopes?
Authors: Bresciani E. , Davy P. , de Dreuzy J.‐R. 
Published: March 2014

AbstractMany physically based hydrological/hydrogeological models used for predicting groundwater seepage areas, including topography‐based index models such as TOPMODEL, rely on the Dupuit assumption. To ensure the sound use of these simplified models, knowledge of the conditions under which they provide a reasonable approximation is critical. In this study, a Dupuit solution for the seepage length in hillslope cross sections is tested against a full‐depth solution of saturated groundwater flow. In homogeneous hillslopes with horizontal impervious base and constant‐slope topography, the comparison reveals that the validity of the Dupuit solution depends not only on the ratio of depth to hillslope length d/L (as might be expected), but also on the ratio of hydraulic conductivity to recharge K/R and on the topographic slope s. The validity of the Dupuit solution is shown to be in fact a unique function of another ratio, the ratio of depth to seepage length d/LS. For d/LS < 0.2, the relative difference between the two solutions is quite small (<14% for the wide range of parameter values tested), whereas for d/LS > 0.2, it increases dramatically. In practice, this criterion can be used to test the validity of Dupuit solutions. When d/LS increases beyond that cutoff, the ratio of seepage length to hillslope length LS/L given by the full‐depth solution tends toward a nonzero asymptotic value. This asymptotic value is shown to be controlled by (and in many cases equal to) the parameter R/(sK). Generalization of the findings to cases featuring heterogeneity, nonhorizontal impervious base and variable‐slope topography is discussed.
Feedbacks between managed irrigation and water availability: Diagnosing temporal and spatial patterns using an integrated hydrologic model
Authors: Condon Laura E. , Maxwell Reed M. 
Published: March 2014

AbstractGroundwater‐fed irrigation has been shown to deplete groundwater storage, decrease surface water runoff, and increase evapotranspiration. Here we simulate soil moisture‐dependent groundwater‐fed irrigation with an integrated hydrologic model. This allows for direct consideration of feedbacks between irrigation demand and groundwater depth. Special attention is paid to system dynamics in order to characterized spatial variability in irrigation demand and response to increased irrigation stress. A total of 80 years of simulation are completed for the Little Washita Basin in Southwestern Oklahoma, USA spanning a range of agricultural development scenarios and management practices. Results show regionally aggregated irrigation impacts consistent with other studies. However, here a spectral analysis reveals that groundwater‐fed irrigation also amplifies the annual streamflow cycle while dampening longer‐term cyclical behavior with increased irrigation during climatological dry periods. Feedbacks between the managed and natural system are clearly observed with respect to both irrigation demand and utilization when water table depths are within a critical range. Although the model domain is heterogeneous with respect to both surface and subsurface parameters, relationships between irrigation demand, water table depth, and irrigation utilization are consistent across space and between scenarios. Still, significant local heterogeneities are observed both with respect to transient behavior and response to stress. Spatial analysis of transient behavior shows that farms with groundwater depths within a critical depth range are most sensitive to management changes. Differences in behavior highlight the importance of groundwater's role in system dynamics in addition to water availability.
Brief communication: Investigation of the semicircular canal variation in the Krapina Neandertals
Authors: Hill Cheryl A. , Radovčić Jakov , Frayer David W. 
Published: March 2014

ABSTRACTPrevious studies comparing bony labyrinth morphology in geographically‐dispersed samples of Neandertals and modern Homo sapiens (H. sapiens) showed that Neandertals generally have smaller semicircular canals than modern H. sapiens (Hublin et al., ; Spoor et al., ; Glantz et al., ). Here we analyze the morphology of a single group of Neandertal specimens from one locale, the Krapina site, to determine the intraspecific variation in Neandertal semicircular canal sizes. Dimensions of the semicircular canals were collected from computed tomography scans of nine temporal bones. With the rare exception, the dimensions of the semicircular canals in the Krapina sample are similar to those previously reported across a geographically‐dispersed sample of Neandertals, further supporting previous studies that suggest low levels of variation in the semicircular canals for Neandertals.

This message will self‐destruct: The growing role of obscurity and self‐destructing data in digital communication
Authors: Kotfila Christopher 
Published: March 2014

AbstractEDITOR'S SUMMARYPeople have traditionally trusted that their private communications were beyond the reach of the public, until technology enabled massive data aggregation. Some information, even if it has been publicly available, is shrouded in “practical obscurity,” because the cost of retrieving it is excessive. But practical obscurity has been diluted by data recording, copying and easy dissemination. The tide is turning with emerging technologies incorporating self‐destruct functionalities that obliterate images, texts, videos and pdfs in a time period specified by the owner. While privacy advocates seek policies protecting information owners from the unintended effects of sharing, policy makers resist limiting industry expansion. Self‐destructing data may provide the solution, shifting control over digital communication back to owners.
Encryption and incrimination: The evolving status of encrypted drives
Authors: Oltmann Shannon M. 
Published: March 2014

AbstractEDITOR'S SUMMARYIndividuals use encryption to safeguard many valid and legal applications but also to hide illegal activity. Several legal cases have drawn the limits of self‐incrimination under the Fifth Amendment regarding providing passwords to access illegal information content, such as child pornography. The cases illustrate that certain knowledge of evidence amounts to a compelling need for access and that a subpoena for hard drive contents is more likely to succeed than requiring a witness to provide a password. Since known documents are not legally protected and biometric data can be compelled as evidence, there is no reason that known digital documents, biometric passwords, and by extension, alphanumeric passwords should not be compelled. Considering precedent and legal doctrine, individuals should resist giving law enforcement any passwords and be wary of sharing them. The question of encryption in criminal cases is under scrutiny and warrants citizens' concern.
