Extrafacial Lentigo Maligna: A Report on 14 Cases and a Review of the Literature
2016
Lentigo maligna is the most common form of in situ melanoma. It is most often found on the head and neck, and its clinical and dermoscopic features in this location have been extensively described in the literature. We present a series of 14 patients diagnosed with extrafacial lentigo maligna and lentigo maligna melanoma at Hospital General de Valencia and Hospital de Manacor in Spain, and describe the clinical, dermoscopic, and histologic features observed. Most of the melanomas were located on the upper limbs; the next most common locations were the trunk and the lower limbs. The dermoscopic patterns were consistent with facial lentigo maligna and superficial spreading melanoma. Extrafaci…
Sentinel Lymph Node Biopsy in Patients With Melanoma
2010
Abstract Introduction and objectives The incidence of melanoma is currently increasing worldwide. One of the factors influencing disease prognosis is the presence of regional lymph node metastases. Sentinel lymph node biopsy attempts to identify subclinical lymph node metastasis as a prognostic factor in the disease. The aim of this study was to analyze differences between patients with melanoma for whom positive or negative results were obtained in sentinel lymph node biopsy and to assess the impact of the technique on disease prognosis. Material and methods Sentinel lymph node biopsy was carried out in patients with melanoma of the following characteristics: Breslow thickness ≥1mm, Breslo…
COOPERATION BETWEEN SPEECH AND LANGUGAGE THERAPIST AND FAMILY TO PROMOTE READING SKILLS IN FIRST GRADE PUPILS
2019
Reading skills are one of essential skills to acquire literacy and be successful in everyday life in school and after it. Literacy skills are complicated for pupils with speech and language disorders, it is responsibility not only of speech and language therapists, but also of family to help these children to become literate. Situation in Latvia is different in different educational institutions, but we have to try our best to involve parents/family to be a part of pupil’s everyday activities.The aim of the article is to state the necessity of cooperation and to explore what kind of cooperation is effective in acquiring reading skills in first grade pupils. Based on the scientific literatur…
Developmental dyslexia and vision
2013
International audience; Developmental dyslexia affects almost 10% of school-aged children and represents a significant public health problem. Its etiology is unknown. The consistent presence of phonological difficulties combined with an inability to manipulate language sounds and the grapheme-phoneme conversion is widely acknowledged. Numerous scientific studies have also documented the presence of eye movement anomalies and deficits of perception of low contrast, low spatial frequency, and high frequency temporal visual information in dyslexics. Anomalies of visual attention with short visual attention spans have also been demonstrated in a large number of cases. Spatial orientation is als…
Temporal profile of gene induction after venous ischemia accompanied by spreading depression as compared to spreading depression alone
2002
Abstract The occlusion of two adjacent cortical veins is followed by a widespread reduction of rCBF and the occurrence of small infarcts, which become larger if spreading depression (SD) occurs. The model appears to be useful for studying penumbra pathophysiology. Here, the time course of gene expression in the penumbra was compared to those induced by the SD alone. In an experiment involving rats, an occlusion of two cortical veins was induced by i.v. rose bengal and fiberoptic illumination. Ten SDs were induced at 7-min intervals. Changes of the gene expression after 2, 8, 24 and 72 h were analysed for 13 genes by RT-PCR. The housekeeping gene glyceraldehyde-3-phosphate dehydrogenase (GAP…
<p>Children with Dyslexia Have Altered Cross-Modal Processing Linked to Binocular Fusion. A Pilot Study</p>
2020
Introduction The cause of dyslexia, a reading disability characterized by difficulties with accurate and/or fluent word recognition and by poor spelling and decoding abilities, is unknown. A considerable body of evidence shows that dyslexics have phonological disorders. Other studies support a theory of altered cross-modal processing with the existence of a pan-sensory temporal processing deficit associated with dyslexia. Learning to read ultimately relies on the formation of automatic multisensory representations of sounds and their written representation while eyes fix a word or move along a text. We therefore studied the effect of brief sounds on vision with a modification of binocular f…
Brain event-related potentials to phoneme contrasts and their correlation to reading skills in school-age children
2017
Development of reading skills has been shown to be tightly linked to phonological processing skills and to some extent to speech perception abilities. Although speech perception is also known to play a role in reading development, it is not clear which processes underlie this connection. Using event-related potentials (ERPs) we investigated the speech processing mechanisms for common and uncommon sound contrasts (/ba/-/da/-/ga/ and /ata/-/at: a/) with respect to the native language of school-age children in Finland and the US. In addition, a comprehensive behavioral test battery of reading and phonological processing was administered. ERPs revealed that the children could discriminate betw…
<title>Eye movements during silent and oral reading with stabilized versus free head movement and different eye-trackers</title>
2008
Eye movement research of reading has been done on a battery of eye-tracking setups during last decades. We compared reading data of the same group of six students, their eyes were tracked by a video-based helmet-mounted system with the data sampling frequency of 50 Hz and a setup with a chin-rest at 240 Hz. We found that not only the number of fixations may decrease after reading practice, but so does also the mean duration of fixations. In spite of the short duration of saccades, their distributions and changes in them are similarly reported in the two experimental conditions. Lack of significant correlation in the HED data testifies to the result variability due to measurement technique. …
Reading ability with 3 multifocal intraocular lens models.
2006
Purpose To prospectively evaluate reading performance with of 3 types of multifocal intraocular lenses (IOLs) under different lighting conditions based on reading acuity and reading speed tests. Setting Augenklinik, Bad Hersfeld, Germany. Methods This randomized study comprised 60 cataract patients (120 eyes) randomly assigned to receive an SA40N IOL (AMO) (Group 1, 20 patients), Tecnis ZM001 IOL (AMO) (Group 2, 20 patients), or AcrySof ReSTOR SA60D3 IOL (Alcon) (Group 3, 20 patients). Pupil size and reading ability at near (visual acuity, reading speed) without correction, with best distance correction, and with best near correction were assessed 6 weeks postoperatively under low-light con…
Time-Course of Grammatical Processing in Deaf Readers: An Eye-Movement Study.
2019
Abstract Twenty participants who were deaf and 20 chronological age-matched participants with typical hearing (TH) (mean age: 12 years) were asked to judge the correctness of written sentences with or without a grammatically incongruent word while their eye movements were registered. TH participants outperformed deaf participants in grammaticality judgment accuracy. For both groups, First Pass and Total Fixation Times of target words in correct trials were significantly longer in the incongruent condition than in the congruent one. However, whereas TH students showed longer First Pass in the target area than deaf students across congruity conditions, deaf students made more fixations than t…
