Planning implant positions for an auricular prosthesis with digital data

The esthetic result of an auricular prosthesis is influenced by the position of the prosthesis incorporating the implants. The entire surface of the patient's head is captured by means of a conventional computed tomography (CT). The digital data are used to mirror the contralateral unimpaired ear for restoration of the impaired side. The virtual ear is integrated into a template covering the auricular defect and indexed to the nasal area with computer-aided technology (CAD/CAM). This virtual template is converted into an acrylic resin template. With that the surgeon and the anaplastologist should determine the optimal implant position of the auricular prosthesis.     

Peri-implantitis in the general oral and maxillofacial surgery practice. A pilot study

A peri-implant infection is a disorder with an annually increasing prevalence and incidence as a result of the increasing number of oral implants utilized. Based on existing literature, a patient-control study was carried out, as a pilot study, among patients who had been treated with oral implants at a department of oral and maxillofacial surgery in a general hospital. Significant relations were found between on the one hand the prevalence of peri-implantitis and on the other hand bone augmentation, a suprastructure of a fixed partial denture or a complete removable overdenture on a ball attachment mesostructure when compared to a crown, poor oral hygiene, poor periodontal condition, and the absence of keratinized mucosa surrounding the implant.     

Extreme attributions predict transition from depression to mania or hypomania in bipolar disorder

Background

Relatively little is known about psychological predictors of the onset of mania among individuals with bipolar disorder, particularly during episodes of depression. In the present study we investigated attributional style as a predictor of onset of hypomanic, manic or mixed episodes among bipolar adults receiving psychosocial treatment for depression. We hypothesized that “extreme” (i.e., excessively pessimistic or optimistic) attributions would predict a greater likelihood of developing an episode of mood elevation.

Method

Outpatients with DSM-IV bipolar I or II disorder (N = 105) enrolled in the Systematic Treatment Enhancement Program for Bipolar Disorder (STEP-BD) were randomly allocated to one of three types of intensive psychotherapy for depression or a brief psychoeducational intervention. Patients completed a measure of attributional style at baseline and were followed prospectively for up to one year. All analyses were by intent to treat.

Results

Logistic regressions and Cox proportional hazards models indicated that extreme (both positively- and negatively-valenced) attributions predicted a higher likelihood of (and shorter time until) transition from depression to a (hypo)manic or mixed episode (ps < .04), independent of the effects of manic or depressive symptom severity at baseline. Extreme attributions were also retrospectively associated with more lifetime episodes of (hypo)mania and depression (ps < .05).

Conclusions

Evaluating extreme attributions may help clinicians to identify patients who are at risk for experiencing a more severe course of bipolar illness, and who may benefit from treatments that introduce greater cognitive flexibility.     

Yes,One Self is Enough!

Although Kohut pointedly differentiated his nascent ideas on narcissistic self-object transferences from Sullivan's participant observation, a close examination shows that their approaches to therapeutic listening are essentially identical. Further, their views on the centrality of the self or self-system in development and psychopathology are also remarkably similar even down to details and nuances. Nonetheless, the two theorists have notably disparate, if potentially complementary, views on anxiety, empathy, and how the self grows. In addition, their respective stances vis-à-vis the role of the self in treatment are surprisingly dissimilar. As background for these comparisons, Sullivan's debts to Cooley, Mead, Meyer, and Bridgman are noted as is Kohut's evolution as a theorist whose essentially relational reinterpretation of narcissism ultimately led him to initiate self psychology.     

Teratogenesis in repeated pregnancies in antiepileptic drug‐treated women

Purpose: Considerable information is now available concerning the risk of teratogenesis in the individual pregnancy exposed to antiepileptic drugs (AEDs). However, there is comparatively little information available concerning the risk in the subsequent pregnancies of women who continue to take the AED associated with a fetal malformation in a previous pregnancy. This article addresses this matter. Methods: Analysis of data concerning fetal abnormalities in 1,243 women who had 2,637 pregnancies between mid‐1999 and 2010 recorded in the Australian Register of Antiepileptic Drugs in Pregnancy. Of the 2,637 pregnancies, 1,114 had been completed before initial enrolment in the Register. Key Findings: Women taking any AED who had given birth to a malformed baby in their first enrolled pregnancy and who continue taking the same drug were at increased risk of having a malformed offspring in their next pregnancy (35.7% vs. 3.1%; odds ratio [OR] 17.6; 95% confidence interval [95% CI] 4.5–68.7). Among these women, those taking valproate (VPA) were more likely to have malformed fetuses in their next pregnancies than those who had taken VPA without fetal abnormalities (57.2% vs. 7.0%, OR 17.8; 95% CI 2.7, 119.1). There were similar although not statistically significant trends in those who had taken AEDs other than VPA. Similar, although again not statistically significant, trends were found, when considering the pairings of the most recent preenrollment pregnancy and the following one. If a woman had two or more pregnancies that resulted in AED‐associated fetal malformation, the types of malformation were often different. Significance: Women whose last pregnancy resulted in a fetal malformation have a substantially increased risk of having further malformed fetuses if they become pregnant again while taking the same AED, particularly VPA. This suggests that maternal factors, perhaps genomic, predispose to at least VPA‐associated malformations. This knowledge, together with information about the outcome of any previous pregnancy, should help in advising women with AED‐treated epilepsy who plan further pregnancies.     

Chance in agrammatic sentence comprehension: What does it really mean? Evidence from eye movements of German agrammatic aphasic patients

Background: In addition to the canonical subject-verb-object (SVO) word order, German also allows for non-canonical order (OVS), and the case-marking system supports thematic role interpretation. Previous eye-tracking studies (Kamide et al., 2003 Kamide, Y., Scheepers, C. and Altmann, G. M. 2003. Integration of syntactic and semantic information in predictive processing: Cross-linguistic evidence from German and English. Journal of Psycholinguistics Research, 32: 37–54. doi: 10.1023/A:1021933015362 [Google Scholar]; Knoeferle, 2007 Knoeferle, P. 2007. “Comparing the time-course of processing initially ambiguous and unambiguous German SVO/OVS sentences in depicted events”. In Eye movement research. A window on mind and brain, Edited by: van Gompel, R., Fischer, M., Murray, W. and Hill, R. 517–531. Oxford, , UK/Amsterdam: Elsevier.  [Google Scholar]) have shown that unambiguous case information in non-canonical sentences is processed incrementally. For individuals with agrammatic aphasia, comprehension of non-canonical sentences is at chance level (Burchert et al., 2003 Burchert, F., De Bleser, R. and Sonntag, K. 2003. Does morphology make the difference? Agrammatic sentence comprehension in German. Brain and Language, 87: 323–342. doi: 10.1016/S0093-934X(03)00132-9[Crossref], [PubMed], [Web of Science ®] , [Google Scholar]). The trace deletion hypothesis (Grodzinsky 1995 Grodzinsky, Y. 1995. A restrictive theory of agrammatic comprehension. Brain and Language, 50: 27–51. doi: 10.1006/brln.1995.1039[Crossref], [PubMed], [Web of Science ®] , [Google Scholar], 2000 Grodzinsky, Y. 2000. The neurology of syntax: Language use without Broca's area. Behavioral and Brain Sciences, 23: 1–71. doi: 10.1017/S0140525X00002399[Crossref], [PubMed], [Web of Science ®] , [Google Scholar]) claims that this is due to structural impairments in syntactic representations, which force the individual with aphasia (IWA) to apply a guessing strategy. However, recent studies investigating online sentence processing in aphasia (Caplan et al., 2007 Caplan, D., Waters, G., DeDe, G., Michaud, J. and Reddy, A. 2007. A study of syntactic processing in aphasia I: Behavioral (psycholinguistic) aspects. Brain and Language, 101: 103–150. doi: 10.1016/j.bandl.2006.06.225[Crossref], [PubMed], [Web of Science ®] , [Google Scholar]; Dickey et al., 2007 Dickey, M. W., Choy, J. J. and Thompson, C. K. 2007. Real-time comprehension of Wh-movement in aphasia: Evidence from eyetracking while listening. Brain and Language, 100: 1–22. doi: 10.1016/j.bandl.2006.06.004[Crossref], [PubMed], [Web of Science ®] , [Google Scholar]) found that divergences exist in IWAs' sentence-processing routines depending on whether they comprehended non-canonical sentences correctly or not, pointing rather to a processing deficit explanation.

Aims: The aim of the current study was to investigate agrammatic IWAs' online and offline sentence comprehension simultaneously in order to reveal what online sentence-processing strategies they rely on and how these differ from controls' processing routines. We further asked whether IWAs' offline chance performance for non-canonical sentences does indeed result from guessing.

Methods & Procedures: We used the visual-world paradigm and measured eye movements (as an index of online sentence processing) of controls (N?=?8) and individuals with aphasia (N?=?7) during a sentence–picture matching task. Additional offline measures were accuracy and reaction times.

Outcomes & Results: While the offline accuracy results corresponded to the pattern predicted by the TDH, IWAs' eye movements revealed systematic differences depending on the response accuracy.

Conclusions: These findings constitute evidence against attributing IWAs' chance performance for non-canonical structures to mere guessing. Instead, our results support processing deficit explanations and characterise the agrammatic parser as deterministic and inefficient: it is slowed down, affected by intermittent deficiencies in performing syntactic operations, and fails to compute reanalysis even when one is detected.     

Sound arithmetic: Auditory cues in the rehabilitation of impaired fact retrieval

The present single case study describes the rehabilitation of an acquired impairment of multiplication fact retrieval. In addition to a conventional drill approach, one set of problems was preceded by auditory cues while the other half was not. After extensive repetition, non-specific improvements could be observed for all trained problems (e.g., 3 × 7) as well as for their non-trained complementary problems (e.g., 7 × 3). Beyond this general improvement, specific therapy effects were found for problems trained with auditory cues. These specific effects were attributed to an involvement of implicit memory systems and/or attentional processes during training. Thus, the present results demonstrate that cues in the training of arithmetic facts do not have to be visual to be effective.
