Background: The general prognostic factors in larynx tumors are believed to be tumor stage, anatomical location, histological differentiation and the presence of neck metastasis. Effects of tumor invasion to sub-regions of larynx (anterior commissure, ventricle, subglottic space) and over-expression of p53, c-erb-B2 and Ki67 detected immunohistochemically on development of recurrence in patients were investigated in this study.
Methods: Twenty patients (Group 1) in whom recurrence had developed and 20 others (Group 2) without recurrence during follow-up were included in this study.
Results: Both the anterior commissure and ventricle involvements were found to be more frequent in patients with recurrence. But statistically significant difference was detected with only ventricular involvement (p=0.025). After Immunohistochemical evaluation none of the 3 immunohistochemical parameters were found to be higher in the recurrence group and not any of them showed a statistically significant difference between two groups.
Conclusion: Only ventricle involvement may be a predictor factor for recurrence.

Tract-specific white matter hyperintensities and neuropsychiatric syndromes: a multicentre memory clinic study.

Background: White matter hyperintensities (WMH) have been implicated in the pathogenesis of neuropsychiatric symptoms of dementia but the functional significance of WMH in specific white matter (WM) tracts is unclear. We investigate whether WMH burden within major WM fibre classes and individual WM tracts are differentially associated with different neuropsychiatric syndromes in a large multicentre study.
Method: Neuroimaging and neuropsychiatric data of seven memory clinic cohorts through the Meta VCI Map consortium were harmonised.

Objetives: Montgomery medialization thyroplasty involves fitting a silicone prosthesis in the thyroid cartilage according to gender-based placement criteria. This standardized procedure can lead in some cases to suboptimal results. The aim of this study is to identify individual anatomical differences between same-gender patients that could explain the occasional failures.

Emerging neurostimulation methods aim to selectively modulate deep brain structures. Guiding these therapies has presented a substantial chal- lenge, since imaging modalities such as MRI limit the spectrum of benefi- ciaries. In this study, we assess the guidance accuracy of a neuronavigation method that does not require taking MRI scans.

Purpose Of Review: To summarize current evidence regarding the indication of adjuvant treatment after transoral laser microsurgery (TOLMS).
Recent Findings: Apart from well known risk factors, margins represent the key point in the decision-making. If margins are affected, additional treatment is mandatory.
Usefulness of the "En face view" method for diagnosing perimembranous ventricular septal defects.

Background: Perimembranous ventricular septal defect (VSD) can be classified as having trabecular, inlet, or outlet extension. The surgical approach used in patch closure depends on the which valve of the tricuspid valve to suture around and the avoidance of the specialized conducting system. This retrospective study evaluated the usefulness of the "En face view" method for classifying perimembranous VSD.
