Parametric change in the grammatical encoding of indirect objects in Brazilian Portuguese

This paper examines the syntax of indirect objects (IO) in Brazilian Portuguese (BP). Adopting a comparative perspective we propose that BP differs from European Portuguese (EP) in the grammatical encoding of IO. In EP ditransitive contexts, IO is found in two configurations - one projected by a (low) applicative head and another one involving a lexical/true preposition. We propose that the former property is contingent upon the presence of dative Case marking: namely, the morpheme `a` that introduces IO (a-DP), whose corresponding clitic pronoun is `lhe/lhes`. In contrast, important changes in the pronominal system, coupled with the increase in the use of the preposition `para` are taken as evidence for the loss of the low applicative construction in BP. Thus only the configuration with the lexical/true preposition is found in (Standard) BP. We argue that the innovative properties of IO in BP are due to the loss of the (3rd person) dative clitic and the preposition `a` as dative Case markers. Under this view, we further account for the realization of IO as a DP/weak pronoun, found in dialects of the central region of Brazil, which points to a similarity with the English Double Object Construction. Finally we show that the connection between the morphological expression of the dative Case and the expression of parameters supports a view of syntactic change according to which parametric variation is determined in the lexicon, in terms of the formal features of functional heads.

T-Shaped Microsuture: A New Suture Technique for Laryngeal Microsurgery

To describe a new suture technique for laryngeal microsurgery and to test its applicability in human cadaver larynges. The new technique was experimentally tested in freshly excised human larynges fixed to a larynx holder appropriate for the simulation of laryngeal microsurgery. A mucosal flap was created in the vocal fold for the fabrication of a pocket for subepithelial fat implantation, and the wound edges were then brought together and sutured using the proposed technique. The time necessary for suture was measured with a stopwatch for five successive sutures performed by one of the surgeons. The presence or absence of mucosal rupture was determined for five sutures performed by two surgeons, for a total of 10 sutures. The sutures were performed without the help of an assistant, with no laceration of the mucosa being observed in any of the attempts, and within a relatively short period of time even without previous training. The sutures performed permitted the implanted fat to remain stable under the mucosal flap. Conclusions: the new suture technique is an easy procedure, which can be performed by a single surgeon under microscopic vision, with a low risk of tissue rupture. The technique does not markedly prolong the duration of surgery and a single suture thread can be used for the fabrication of more than one stitch.

Voice Feature Characteristic in Morbid Obese Population

Morbid obesity is highly prevalent in the Western World, and its consequences present a real public health challenge. Voice alterations can represent one of these consequences and represent an opportunity for interference with therapeutic methods. This particularly features of the individual`s voice was the goal of the present study. A group of 45 adult volunteers of both sexes with a BMI greater than 35 Kg/m(2) was selected among patients of the Obesity Ambulatory of the Digestive Surgery Division. The control group consisted of volunteers matched by sex, age (+/- 1 year), and smoking habits, but with a BMI bellow 30 Kg/m(2). All subjects were submitted to laryngoscopic examination, audio perceptive analysis, and voice acoustics determination. Examinations were always performed by the same doctor, and diagnoses were provided by two different physician specialists in laryngology and voice. Obese individuals exhibit the following modifications in voice feature: hoarseness, murmuring, vocal instability, altered jitter and shimmer, and reduced maximum phonation times as well the presence of voice strangulation at the end of emission. The voices of individuals with morbid obesity are different of the voice of nonobese people and demonstrate significant changes in vocal characteristics.

Evaluation of inverted papilloma and squamous cell carcinoma by nasal contact endoscopy

Background: Contact endoscopy (CE) was initially described as a method used in the analysis of uterine and vocal folds histology. The first nasal cavity CE studies achieved promising results regarding its use for the differentiation between benign and malignant lesions, considering that biopsy might cause some complications, especially bleeding. This study described and compared the findings of CE on inverted papilloma and nasosinusal squamous cell carcinoma (SCC) and tested the effectiveness of this exam as a noninvasive method for in vivo differentiation between these tumors. Methods: The patients included in this study were divided into group A, patients diagnosed with inverted papilloma, and group B, patients diagnosed with SCC. CE results were compared among themselves. CE images were presented to examiners not experienced with the method. Results: Twenty-two patients were examined, 13 in group A and 9 in group B. The main relevant differences in CE findings between those two groups were corkscrew vessels, presence of mitoses, keratinization and nuclear pleomorphism in carcinoma, and vacuolated cells in papilloma. The examiners were capable of defining the diagnosis of these nasal tumors only based on CE images. Conclusion: CE may be a useful noninvasive exam to be used in the in vivo diagnosis of inverted papilloma and nasosinusal SCC, which may enable better preoperative planning.

Metallic Voice: Physiological and Acoustic Features

The metallic voice is usually confused with ring or nasality by singers and nontrained listeners. who are not used to perceptual vocal analysis. They believe a metallic voice results from a rise in fundamental frequency. A diagnostic error in this aspect may lead to lowering pitch, an incorrect procedure that Could Cause vocal overload and fatigue. The purpose of this article is to Study the quality of metallic voice considering the correlation between information of the physiological and acoustic plans, based on a perceptive consensual assumption. Fiberscopic video pharyngolaryngoscopy was performed on 21 professional singers while speaking vowel [e]-in normal and metallic modes to observe muscular movements and structural changes of the velopharynx, pharynx, and larynx. Vocal samples captured simultaneously to the fiberscopic examination were acoustically analyzed. Frequency and amplitude of the first four formants (F(1), F(2), F(3), and F(4)) were extracted by means of linear predictor coefficients (LPC) Spectrum and were statistically analyzed. Vocal tract adjustments such as velar lowering, pharyngeal wall narrowing, laryngeal rise, aryepiglottic, and lateral laryngeal constrictions were frequently found: there were no significant changes in frequency and amplitude of F(1) in the metallic voiced there were significant increases in amplitudes of F(2), F(3), and F(4) and in frequency for F, metallic Voice perceived as louder was correlated to an increase ill amplitude of F(3) and F(4). Physiological adjustments of velopharynx, pharynx, and larynx are combined in characterizing the metallic voice and can be acoustically related to changes in formant pattern.

Quantitative Analysis of Placental Vasculature by Three-Dimensional Power Doppler Ultrasonography in Normal Pregnancies From 12 to 40 Weeks of Gestation

Evaluate the distribution and variation of placental vascular indices according to gestational age and placental volume. From March to November 2007, three-dimensional (3D)-power Doppler ultrasound was performed in 295 normal pregnancies from 12 to 40 weeks of gestation. Using the same preestablished settings for all patients, power Doppler was applied to the placenta and placental Volume was obtained by the rotational technique (VOCAL(TM)). The 3D-power histogram was used to determine the placental vascular indices: vascularization index (VI), flow index (FI) and vascularization-flow index (VFI). The placental vascular indices were then plotted against gestational age and placental volume. All placental vascular indices showed constant distribution throughout gestation. A tendency for a reduction in placental vascular indices with increased placental volume was observed, but was only statistically significant when placental FI was considered (p < 0.05). All placental vascular indices estimated by 3D-power Doppler ultrasonography presented constant distribution throughout gestation, despite the increase in placental volume according to gestational age.

Disarrangement of Collagen Fibers in Reinke`s Edema

Objective/Hypothesis: To describe the arrangement of collagen fibers in the superficial layer of the lamina propria of the vocal folds with Reinke` edema. Study Design: Cross sectional analysis of the lamina propria of the vocal folds with Reinke`s edema (RE). Method: The picrosirius polarization method was used to study the arrangement of collagen fiber. Findings of collagen disarrangement were categorized semiquantitatively and correlated with RE severity, age, cigarette smoking and duration of dysphonia. Results: Analysis of 20 specimens of vocal folds with RE showed that the intertwined network of collagen fibers resembling a wicker-basket normally observed in vocal folds was disarranged in RE. The collagen fibers were loosely arranged, fragmented and intermixed with varying amounts of myxoid stroma. Moderate and large areas of disarrangement (90% of cases) predominated. Collagen fiber arrangement in the region underneath the epithelium was better preserved when compared with fibers in the deeper region of the superficial layer of the lamina propria. There was a statistical difference in collagen disarrangement between grade II and grade III severity (P = .007) that appeared to be due to the large areas of disarrangement observed in 73% of patients with grade III severity and in 44% of grade II severity. Age was the only variable correlated with collagen fiber disarrangement (r = 0.47, P = .037). Conclusion: Our findings suggest that the flexible framework which maintains the uniformity of the lamina propria was lost in RE caused by the disarrangement of the collagen fibers.

Elastic Fibers in Reinke`s Edema

Objectives: We describe the distribution of elastic system fibers in the superficial layer of the lamina propria of Reinke`s edema, as compared with normal vocal folds. Methods: Weigert`s resorcin-fuchsin stain after oxidation with 10% oxone was used to study the arrangement of elastic fibers. The findings were categorized and afterward compared with the severity of Reinke`s edema. Results: Analysis of 20 specimens of vocal folds with Reinke`s edema showed that the network of thin elastic fibers in Reinke`s space lost their undulated appearance and had a tangled aspect. In addition, these fibers were no longer parallel to the epithelial basement membrane, but had a random distribution scattered throughout Reinke`s space. The elastic fiber network immediately below the epithelial basement membrane also appeared more fragmented in Reinke`s edema because of some alteration in organization combined with the 5-mu m-thick histologic sectioning plane. No significant difference in the degree of elastic system fiber disarrangement was observed between severity grades II and III (p = 0.382). Large areas of disarrangement were predominant (80% of cases). Conclusions: The disarrangement of elastic fibers in Reinke`s edema may cause insufficient tissue resistance and resilience, contributing to the hypermobility observed in Reinke`s edema.

Relation between Videofluoroscopy of the Esophagus and the Quality of Esophageal Speech

The goal of the current study was to compare the quality of esophageal speech and voice to videofluoroscopic features of the esophagus and pharyngoesophageal (PE) segment. The speech and voice characteristics of 30 laryngectomized patients were rated by 5 speech-language pathologists. Based on these ratings, patients were divided into 3 categories: fluent (n = 9), moderately fluent (n = 10) and nonfluent (n = 11). Videofluoroscopy of the PE region was then performed during both swallowing and voice production. An insufflation test and percutaneous pharyngeal plexus block were required in 9 patients to determine the etiology of poor esophageal voice production. The strongest videofluoroscopic indicators of nonfluent speakers were: (1) small or absent air reservoir and (2) lack of a vibrating PE segment. Fluent speakers presented with shorter PE segments (1.17 mm) compared to moderately fluent speakers (17.1-29.9 mm). Perceptually, fluent speakers presented with a predominantly rough vocal quality. In contrast, moderately fluent speakers presented with a tense quality. In addition, stoma blast noise was reduced in fluent speakers. Videofluoroscopic findings highly correlated with the quality of esophageal speech. Copyright (C) 2009 S. Karger AG, Basel

Inhibitory network interactions shape the auditory processing of natural communication signals in the songbird auditory forebrain

The role of GABA in the central processing of complex auditory signals is not fully understood. We have studied the involvement of GABA(A)-mediated inhibition in the processing of birdsong, a learned vocal communication signal requiring intact hearing for its development and maintenance. We focused on caudomedial nidopallium (NCM), an area analogous to parts of the mammalian auditory cortex with selective responses to birdsong. We present evidence that GABA(A)-mediated inhibition plays a pronounced role in NCM`s auditory processing of birdsong. Using immunocytochemistry, we show that approximately half of NCM`s neurons are GABAergic. Whole cell patch-clamp recordings in a slice preparation demonstrate that, at rest, spontaneously active GABAergic synapses inhibit excitatory inputs onto NCM neurons via GABA(A) receptors. Multi-electrode electrophysiological recordings in awake birds show that local blockade of GABA(A)-mediated inhibition in NCM markedly affects the temporal pattern of song-evoked responses in NCM without modifications in frequency tuning. Surprisingly, this blockade increases the phasic and largely suppresses the tonic response component, reflecting dynamic relationships of inhibitory networks that could include disinhibition. Thus processing of learned natural communication sounds in songbirds, and possibly other vocal learners, may depend on complex interactions of inhibitory networks.

Variations of Jitter and Shimmer Among Women in Menacme and Postmenopausal Women

The objective of the study was to analyze comparatively the jitter and shimmer values of spoken voice among women in menacme and menopausal women using or not hormonal replacement therapy (HRT). Forty-five women were studied, divided into the following groups: Control Group (CG), 15 women aged 20-40 years with regular menstrual cycles who did not take hormonal contraceptives, Treated Group (TG), 15 women aged 45-60 years with at least 2 years of menopause, under continuous HRT with I mg estradiol valerate + 90 mu g norgestimate per day for at least 6 months; Untreated Group (UG), 15 women aged 45-60 years with at least 2 years of menopause who did not use HRT. Mean age was 30.3, 54.5, and 56.5 years for CG, TG, and UG, respectively. All subjects were submitted to acoustic analysis of jitter and shimmer for the sustained vowels /e/ and /i/. Mean jitter values were 0.56%, 0.64%, and 0.56% for the vowel /e/ and 0.88%, 0.79%, and 0.68% for the vowel /i/ for CG, TG, and UG, respectively. Mean shimmer values were 4.17%, 4.38%, and 4.77% for the vowel /e/ and 5.19%, 4.59%, and 5.37% for the vowel /i/ for CG, TG, and UG, respectively. There were no significant differences between the groups studied. The results obtained here by the methodology used suggest that there were no significant differences in jitter and shimmer when we assessed the sustained vowels /i/ and /e/ between menopausal women using or not HRT or between young and menopausal women treated or not.

A standardized measurement technique may improve the reliability of measurements of endometrial thickness and volume

Objective To investigate whether standardization of the multiplanar view (SMV) when evaluating the uterus using three-dimensional ultrasonography (3D-US) improves intra-and interobserver reliability and agreement with regard to endometrial measurement. Methods Two-dimensional (2D) and 3D-US was used to measure endometrial thickness by two observers in 30 women undergoing assisted reproduction treatment. Endometrial volume was measured with Virtual Organ Computer-aided AnaLysis (VOCAL (TM)) in the longitudinal (A) and coronal (C) planes using an unmodified multiplanar view (UMV) and a standardized multiplanar view (SMV). Measurement reliability was evaluated by intraclass correlation coefficient (ICC) and agreement was examined using Bland-Altman plots with limits of agreement (LoA). The ease of outlining the endometrial-myometrial interface was compared between the A-and C-planes using subjective assessment. Results Endometrial volume measurements using the SMV and A-plane were more reliable (intra-and interobserver ICCs, 0.979 and 0.975, respectively) than were measurements of endometrial thickness using 2D-US (intra-and interobserver ICCs, 0.742 and 0.702, respectively) or 3D-US (intra-and interobserver ICCs, 0.890 and 0.784, respectively). The LoAs were narrower for SMV than for UMV. Reliability and agreement were not much different between the A- and C-planes. However the observers agreed that delineating the endometrial-myometrial interface using the A-plane was easier (first and second observer, 50.0 and 46.7%, respectively) or `comparable` (50 and 53.3%, respectively), but never more difficult than using the C-plane. Conclusions Endometrial volume measurements are more reliable than endometrial thickness measurements and are best performed using SMV and the A-plane. Copyright (C) 2011 ISUOG.

Fetal volume and crown-rump length from 7 to 10 weeks of gestational age in singletons and twins

Objective(s): We intend to verify if fetal volume and crown-rump length were different between singletons and twins in pregnancies aged from 7 to 10 weeks and to evaluate if fetal volume is more accurate to determine the gestational age than crown-rump length at this gestational age. Study design: From 52 days (7 weeks and 3 days) to 73 days (10 weeks and 3 days) weekly three-dimensional Ultrasonography was per-formed in 20 twin fetuses and 20 singletons. Crown-rump length and fetal volume using VOCAL were assessed in all examinations. The `true` gestational age was based on oocyte retrieval. Results: At the age of 52 days, the crown-rump length was 11.74 +/- 0.27 mm (mean +/- S.D.) and 11.48 +/- 0.22 mm (singletons and twins, respectively), while the fetal volume was 0.354 +/- 0.015 cm(3) and 0.324 +/- 0.012 cm(3). At the gestational age of 73 days, the crown-rump length was 36.19 +/- 0.90 mm and 35.87 +/- 0.54 mm and the fetal volume was 6.204 +/- 0.090 cm(3) and 6.083 +/- 0.081 cm(3). The total relative increase observed was much higher for fetal volume than for CRL: 1705 +/- 301% vs. 210 +/- 33% in singletons and 1827 +/- 305% vs. 214 +/- 25% in twins. The 95% limits of agreement (+/- 2.3 days vs. +/- 3.2 days, fetal volume vs. crown-rump length) and the intraclass correlation coefficients (0.989 vs. 0.978) between the ""true"" gestational age and that predicted by fetal volume were better than those predicted by crown-rump length. No significant difference was identified between singletons and twins for both fetal volume and crown-rump length. Conclusion(s): Twins and singletons had similar fetal volume and crown-rump length between the 7th and 10th week of gestational age. Additionally, fetal volume assessed by VOCAL was better than crown-rump length to estimate the gestational age at the evaluated period. However, the improvement was small and probably without clinical significance. Condensation: Fetal volume and crown-rump length were similar between singletons and twins. Fetal volume relative increase was higher and the predicted gestational age was better. (c) 2009 Elsevier Ireland Ltd. All rights reserved.

First trimester fetal volume and crown-rump length: Comparison between singletons and twins conceived by in vitro fertilization

The aim of this study was to compare the crown-rump length (CRL) and the fetal head and trunk (HT) volume between singletons and twins conceived after in vitro fertilization. Thirty pregnant patients submitted to embryo transfer were enrolled in this research. Ten conceived twins (20 dichorionic fetuses) while other 20 conceived singletons. The gestational age was calculated by adding 14 d to the number of days between the oocyte retrieval and the scheduled ultrasound. Three-dimensional ultrasound scans were performed weekly from 73 d (10 wk and 3 d) to 101 d (14 wk and 3 d) of gestational age. HT volume was assessed by VOCAL using 15 degrees step rotation on the manual mode. The measurement of CRL was performed by using the longitudinal plane of the fetus in the multiplanar view. The CRL and HT volume weekly relative increase were evaluated to compare the growth between singletons and twins. No significant difference was identified, in any analyzed week, when comparing the mean of CRL and HT volume between singletons and twins. Additionally, no significant difference between singletons and twins was noticed when comparing the weekly relative increase, both for CRL and HT volume. However, the weekly relative increase was significantly higher for HT volume than for CRL in every week studied for both singletons and twins. The total relative increase observed between 73 and 101 d was much higher for HT volume than for CRL: 679 +/- 39% versus 138 +/- 18% in singletons and 689 +/- 58% versus 139 +/- 21% in twins (HT volume and CRL, respectively), suggesting that HT volume could more accurately determine the gestational age.

Language and disability in Japan

Language relating to disability in the public arena has been a sensitive issue in Japan as elsewhere. Since the 1970s and 80s, major media organisations have replaced words considered derogatory with more acceptable equivalents; laws, statutes and other legal documents have likewise been revised. This article examines how the language used to portray people with disabilities has changed, how the changes came about and how they were received. The debate has largely been played out in four public spaces, which to some extent intersect and overlap: the media (both print and visual), the laws, literature and, increasingly now, the Internet. I argue that while the laws were rewritten primarily as the result of external international trends, such as the International Year of Disabled Persons, disability groups achieved media compliance mainly by exploiting the keen desire of Japanese media organisations to avoid public embarrassment resulting from vocal protests over infractions.
