The Endocrown: An Alternative Approach for Restoring Extensively Damaged Molars
Authors: Biacchi Gislaine Rosa , Mello Beatriz , Basting Roberta Tarkany 
Published: October 2013

AbstractEndocrown‐type restorations are single prostheses fabricated from reinforced ceramics that can be acid etched, indicated for endodontically treated molar teeth that have significant loss of coronal structure. Endocrowns are formed from a monoblock containing the coronal portion integrated into the apical projection that fills the pulp chamber space, and possibly the root canal entrances. In this study, the proposal was to discuss the indication and use of the endocrown to replace single crowns with intraradicular retention, and to present a clinical case report on the 3‐year follow‐up of an endocrown‐type restoration, fabricated from injected lithium disilicate ceramic (IPS e.Max Press/Ivoclar Vivadent) in a mandibular first molar with extensive coronal destruction from fracture. It was found that endocrown restorations could be made following the development of reinforced ceramics that can be acid etched, that have aggregate strength and esthetics, that bond to the dental structure, and that have developed from broader knowledge of the biomechanical behavior of depulped teeth restored with and without intraradicular posts. Clinical studies have shown that the endocrown has functional longevity, and has become a promising alternative in the esthetic and functional recovery of endodontically treated molar teeth.Clinical SignificanceIt should be borne in mind that endocrowns offer advantages for the restoration of depulped molar teeth, insofar as they promote adequate function and offer adequate esthetics, and also maintain the biomechanical integrity of the compromised structure of non‐vital posterior teeth. By eliminating the use of a post and filling core, the number of adhesive bond interfaces is reduced, thus making the restoration less susceptible to the adverse effects of degradation of the hybrid layer. In this clinical case, the 3‐year survival of the endocrown restoration may be considered successful.
Schmidingerothrix salinarum nov. spec. is the Molecular Sister of the Large Oxytrichid Clade (Ciliophora, Hypotricha)
Authors: Foissner Wilhelm , Filker Sabine , Stoeck Thorsten 
Published: October 2013

AbstractIn 2012, Foissner described a curious hypotrich: Schmidingerothrix extraordinaria. This ciliate, which he discovered in hypersaline soils (~100‰) from Namibia, had a frayed buccal lip, three‐rowed adoral membranelles, only one frontal cirrus, and a miniaturized first frontal membranelle, while a paroral membrane, dorsal bristle rows and buccal, transverse and caudal cirri were absent. All opisthe structures developed de novo, while parental structures were involved in the proter. When Foissner's study became available, we discovered a similar species in a Portuguese solar saltern, differing from S. extraordinaria mainly by the number of frontoventral cirral rows (3 vs. 1). Furthermore, parental structures were involved in the ontogenesis of both proter and opisthe. The small subunit (SSU) rDNA shows Schmidingerothrix as sister of a large clade containing most classical oxytrichids (e.g. Sterkiella, Oxytricha, Steinia) and many related taxa (e.g. Pattersoniella, Bistichella, Uroleptus). This clade shows a bifurcation named “Oxytricha subclade” and “Uroleptus subclade”. Foissner () interpreted the peculiarities of Schmidingerothrix as a reduction caused by the extreme habitat. However, the molecular data do not exclude that Schmidingerothrix presents an ancient state. A morphology‐based scheme is presented, showing how the subclades might have evolved from a Schmidingerothrix‐like ancestor.
Extragonadal omental teratoma: A case report
Authors: Hegde Prashanth 
Published: October 2013

AbstractMature cystic teratomas or dermoid cysts are among the most common ovarian tumors; however, teratomas of extragonadal origin are extremely rare. The most common extragonadal site of these teratomas is the omentum. It is generally accepted that teratomas arise from germ cells that originate in the mature gonads. Of the three proposed causes of omental teratoma, auto‐amputation and subsequent re‐implantation of gonadal teratoma is the most likely preceding event. A review of the published reports reveals that only 31 cases of teratoma of the greater omentum have been published to date and three cases reported wherein omental teratoma and dermoid of the ovary were coexisting. We report a rare case of an omental teratoma in a 26‐year‐old woman who underwent ovarian cystectomy for dermoid cyst. This is the fourth case of an omental mature teratoma with coexisting ovarian dermoid cyst.

Published: October 2013

AbstractDouble gynecologic cancer (primary cancers in two organs) is relatively rare. However, triple gynecologic cancer (primary cancers in three organs) is extremely rare. We experienced a case of triple cancer, with primary cervical, endometrial and ovarian cancers, each showing different histopathological features. A 50‐year‐old woman with a preoperative diagnosis of cervical cancer stage Ib1 with a pathological diagnosis of mucinous adenocarcinoma underwent radical hysterectomy. The pathological diagnoses of the extracted masses were endometrioid adenocarcinoma in the uterine corpus and serous adenocarcinoma in the left ovary. Consequently, triple cancer was diagnosed. After the operation, six cycles of a paclitaxel/carboplatin regimen were administered, and no relapse of the cancers has been observed to date. To our knowledge, this is only the second case report in the international literature of concurrent gynecologic triple cancers of epithelial origin; that is, invasive cervical, endometrial and ovarian cancers, each with different histopathological features.

Published: October 2013

AbstractAimTo compare the effectiveness of the double cervical cerclage method versus the single method in women with recurrent second‐trimester delivery.MethodIn this randomized clinical trial, we included 33 singleton pregnancies suffering from recurrent second‐trimester pregnancy loss (≥2 consecutive fetal loss during second‐trimester or with a history of unsuccessful procedures utilizing the McDonald method), due to cervical incompetence. Patients were randomly assigned to undergo either the classic McDonald method (n = 14) or the double cerclage method (n = 19). The successful pregnancy rate and gestational age at delivery was also compared between the two groups.ResultsThe two study groups were comparable regarding their baseline characteristics. The successful pregnancy rate did not differ significantly between those who underwent the double cerclage method or the classic McDonald cerclage method (100% vs 85.7%; P = 0.172). In the same way, the preterm delivery rate (<34 weeks of gestation) was comparable between the two study groups (10.5% vs 35.7%; P = 0.106). Those undergoing the double cerclage method had longer gestational duration (37.2 ± 2.6 vs 34.3 ± 3.8 weeks; P = 0.016).ConclusionThe double cervical cerclage method seems to provide better cervical support, as compared with the classic McDonald cerclage method, in those suffering from recurrent pregnancy loss, due to cervical incompetence.

Published: October 2013

AbstractAimTo evaluate and compare analgesic efficacy, drug consumption and patient satisfaction with the i.v. patient‐controlled and continuous infusion modes of administration of tramadol.MethodsA total of 40 pregnant women in American Society of Anesthesiologists physical status classification system risk classes I–II scheduled for cesarean section were randomized into two groups to receive treatment in single‐blind fashion. Patients in both groups received tramadol as an i.v. infusion 15 min before the end of surgery under general anesthesia for cesarean section. In the post‐anesthesia care unit, the 20 patients allocated to group I were given i.v. tramadol in patient‐controlled anesthesia (PCA), while the 20 other patients assigned to group II received it as a continuous infusion. Pain visual analog scores (VAS), mean arterial pressure (MAP), heart rate, total tramadol consumption, sedation scores, side‐effects (nausea/vomiting) and patient satisfaction were evaluated seven times in the course of the first postoperative 24 h. The Mann–Whitney U‐test and Friedman's anova were used for the statistical treatment of data.ResultsVAS, sedation scores and nausea/vomiting scores were similar in both groups (P > 0.05). The 24‐h tramadol consumption was significantly lower in group I (420.15 ± 66.58 mg) than in group II (494.00 ± 29.45 mg), while patient satisfaction was significantly higher in group I (P < 0.05).ConclusionWhile tramadol administration by either of the methods used may ensure efficient early postoperative anesthesia in cesarean section patients, i.v. PCA may be preferred because of the lower drug consumption and higher patient satisfaction associated with it.

Authors: Bayoğlu Tekin Yeşim , Suat Dede Faruk 
Published: October 2013

AbstractAimTo assess the diagnostic accuracy of the ultrasonographic discrimination of benign adnexal masses.MethodsThis was a prospective study, evaluating 245 consecutive cases using real‐time gray‐scale ultrasonography in a tertiary education hospital.ResultsDiagnostic accuracy was high for simple cysts and solid masses as κ‐values of 0.824 and 0.816 and accuracy was moderate for endometriomas, dermoid cysts and cystadenomas as κ‐values of 0.758, 0.689 and 0.627, respectively, and low for hemorrhagic cysts as a κ‐value of 0.587. A logistic regression model was developed using ultrasonographic characteristics of the adnexal masses. Irregularity at lining of the inner wall, presence of solid component, papillary projections and echogenicity were shown to have a strong impact on the diagnosis of benign masses.ConclusionAlthough ultrasonography is a useful technique for the diagnosis of benign adnexal masses, it is limited in diagnostic accuracy. Pattern recognition is the most favored method for ultrasonographic diagnosis. Logistic regression analysis can contribute to diagnostic accuracy.

AbstractAimThe aim of this study was to determine the frequency of various symptoms and their associated characteristics in women with adenomyosis who underwent hysterectomy, and to determine which symptoms are likely to go with which others in these patients.Material and MethodsIn 2007, 1697 consecutive patients underwent hysterectomy in our hospital. Among them, 734 (43.3%) were histologically confirmed to have adenomyosis, and 710 of them were premenopausal. The medical charts of all 734 patients were retrieved, and their demographic, clinical information and postoperative findings were recorded. We used the Verbal Descriptor Scale to measure the preoperative severity of dysmenorrhea. The Apriori Algorithm was used for mining the association of different symptoms.ResultsAmong the 710 premenopausal patients, only 4.5% of them had no symptoms. Dysmenorrhea was the most common complaint, occurring in 81.7% of patients. Dysmenorrhea co‐occurred most frequently with menorrhagia. The presence of adhesion, presence of endometriosis, complaint of menorrhagia, longer duration of disease, gravidity, palpable pain during pelvic examination, and diffuse adenomyosis were positively associated with the severity of dysmenorrhea. Age, severity of dysmenorrhea, and complaint of metrorrhagia were positively associated with the risk of menorrhagia.ConclusionsDysmenorrhea is the most common complaint in women with adenomyosis, which often goes with that of menorrhagia. Adenomyosis often co‐occurs with endometriosis and leiomyomas. Various factors are associated with the risk of having different symptoms.

AbstractThe elemental composition of strawberry plants (Fragaria ananassacv.Macarena) inoculated with the plant growth‐promoting bacteriumAzospirillum brasilenseREC3, and non‐inoculated controls, was studied using scanning electron microscopy (SEM) and energy dispersiveX‐ray (EDS) analysis. This allowed simultaneous semi‐quantification of different elements in a small, solid sample. Plants were inoculated and grown hydroponically in 50% or 100%Hoagland solution, corresponding to limited or optimum nutrient medium, respectively. Bacteria‐inoculated plants increased the growth index 45% and 80% compared to controls when grown in 100% and 50% Hoagland solution, respectively. Thus, inoculation withA. brasilenseREC3 in a nutrient‐limited medium had the strongest effect in terms of increasing both shoot and root biomass and growth index, as already described forAzospirilluminoculated into nutrient‐poor soils.SEM‐EDSspectra and maps showed the elemental composition and relative distribution of nutrients in strawberry tissues. Leaves containedC,O,N,Na,P,K,Ca andCu, while roots also hadSi andCl. The organic fraction (C,OandN) accounted for over 96.3% of the total chemical composition; of the mineral fraction, Na had higher accumulation in both leaves and roots.Azospirillum‐inoculated and control plants had similar elemental quantities; however, in bacteria‐inoculated roots,Pwas significantly increased (34.33%), which constitutes a major benefit for plant nutrition, whileCu content decreased (35.16%).
Are two threats worse than one? The effects of face race and emotional expression on fear conditioning
Authors: Bramwell Shannon , Mallan Kimberley M. , Lipp Ottmar V. 
Published: October 2013

AbstractFacial cues of racial outgroup or anger mediate fear learning that is resistant to extinction. Whether this resistance is potentiated if fear is conditioned to angry, other race faces has not been established. Two groups of Caucasian participants were conditioned with two happy and two angry face conditional stimuli (CSs). During acquisition, one happy and one angry face were paired with an aversive unconditional stimulus whereas the second happy and angry faces were presented alone. CS face race (Caucasian, African American) was varied between groups. During habituation, electrodermal responses were larger to angry faces regardless of race and declined less to other race faces. Extinction was immediate for Caucasian happy faces, delayed for angry faces regardless of race, and slowest for happy racial outgroup faces. Combining the facial cues of other race and anger does not enhance resistance to extinction of fear.
Real Convergence, Capital Flows, and Competitiveness in Central and Eastern Europe
Authors: Belke Ansgar , Schnabl Gunther , Zemanek Holger 
Published: October 2013

AbstractThe paper scrutinizes the role of capital flows for competitiveness in the new EU member states in the context of real convergence. For this purpose it extends the seminal Balassa–Samuelson model by international capital markets to trace cyclical deviations of real exchange rates from the productivity‐driven equilibrium path. Panel estimations for the period from 1998 to 2009 reveal strong evidence for the Balassa–Samuelson effect and mixed results for the role of capital flows for international competitiveness of the Central and Eastern European countries.
Mode of International Investment and Endogenous Risk of Expropriation
Authors: Dadasov Ramin , Lorz Oliver 
Published: October 2013

AbstractThis paper analyzes the relationship between the mode of international investment and institutional quality. Foreign investors from a capital‐rich North can either purchase productive assets in a capital‐poor South and transfer their capital within integrated multinational firms or they can form joint ventures with local asset owners. The South is ruled by an autocratic elite that may use its political power to expropriate productive assets. The expropriation risk lowers the incentive to provide specific capital in an integrated firm and distorts the decision between joint ventures and integrated production. We determine the equilibrium risk of expropriation in this framework and the resulting pattern of international production. We also analyze as to how globalization, which is reflected in a decline in investment costs, influences institutional quality.
Development and implementation of a remote audit tool for high dose rate (HDR) Ir‐192 brachytherapy using optically stimulated luminescence dosimetry

Published: October 2013

Purpose:The aim of this work was to create a mailable phantom with measurement accuracy suitable for Radiological Physics Center (RPC) audits of high dose‐rate (HDR) brachytherapy sources at institutions participating in National Cancer Institute‐funded cooperative clinical trials. Optically stimulated luminescence dosimeters (OSLDs) were chosen as the dosimeter to be used with the phantom.Methods:The authors designed and built an 8 × 8 × 10 cm3 prototype phantom that had two slots capable of holding Al2O3:C OSLDs (nanoDots; Landauer, Glenwood, IL) and a single channel capable of accepting all 192Ir HDR brachytherapy sources in current clinical use in the United States. The authors irradiated the phantom with Nucletron and Varian 192Ir HDR sources in order to determine correction factors for linearity with dose and the combined effects of irradiation energy and phantom characteristics. The phantom was then sent to eight institutions which volunteered to perform trial remote audits.Results:The linearity correction factor waskL = (−9.43 × 10−5 × dose) + 1.009, where dose is in cGy, which differed from that determined by the RPC for the same batch of dosimeters using 60Co irradiation. Separate block correction factors were determined for current versions of both Nucletron and Varian 192Ir HDR sources and these vendor‐specific correction factors differed by almost 2.6%. For the Nucletron source, the correction factor was 1.026 [95% confidence interval (CI) = 1.023–1.028], and for the Varian source, it was 1.000 (95% CI = 0.995–1.005). Variations in lateral source positioning up to 0.8 mm and distal/proximal source positioning up to 10 mm had minimal effect on dose measurement accuracy. The overall dose measurement uncertainty of the system was estimated to be 2.4% and 2.5% for the Nucletron and Varian sources, respectively (95% CI). This uncertainty was sufficient to establish a ±5% acceptance criterion for source strength audits under a formal RPC audit program. Trial audits of four Nucletron sources and four Varian sources revealed an average RPC‐to‐institution dose ratio of 1.000 (standard deviation = 0.011).Conclusions:The authors have created an OSLD‐based192Ir HDR brachytherapy source remote audit tool which offers sufficient dose measurement accuracy to allow the RPC to establish a remote audit program with a ±5% acceptance criterion. The feasibility of the system has been demonstrated with eight trial audits to date.
On the temporal window of auditory-brain system in connection with subjective responses
Authors: Mouri Kiminori 
Published: October 2013

The human auditory-brain system processes information extracted from autocorrelation function (ACF) of the source signal and interaural cross correlation function (IACF) of binaural sound signals which are associated with the left and right cerebral hemispheres, respectively. The purpose of this dissertation is to determine the desirable temporal window (2T: integration interval) for ACF and IACF mechanisms. For the ACF mechanism, the visual change of Φ(0), i.e., the power of ACF, was associated with the change of loudness, and it is shown that the recommended temporal window is given as about 30(τe)min [s]. The value of (τe)min is the minimum value of effective duration of the running ACF of the source signal. It is worth noticing from the experiment of EEG that the most preferred delay time of the first reflection sound is determined by the piece indicating (τe)min in the source signal. For the IACF mechanism, the temporal window is determined as below: The measured range of τIACC corresponding to subjective angle for the moving image sound depends on the temporal window. Here, the moving image was simulated by the use of two loudspeakers located at ±20° in the horizontal plane, reproducing amplitude modulated band-limited noise alternatively. It is found that the temporal window has a wide range of values from 0.03 to 1 [s] for the modulation frequency below 0.2 Hz.
