RESUMO
PURPOSE: This study aims to identify eye-gaze control technology outcomes, parent perception of the technology and support received, and gauge the feasibility of available measures. METHODS: Five children with dyskinetic cerebral palsy, mean age 4 years, 4 months (1 year, 0 months); n = 4 males; trialled two eye-gaze control technology systems, each for six weeks. Parents completed pre- and post-questionnaires. RESULTS: Parents found the 6-week home-based trial period to be the right length. Written guidelines and instructions about set-up, calibration, and play and learning activities were perceived as important. Children demonstrated improvements in goal achievement and performance. Parents found questionnaires on quality of life, participation, behaviours involved in mastering a skill and communication outcomes challenging to complete resulting in substantial missing data. CONCLUSION: Eye-gaze control technology warrants further investigation for young children with dyskinetic cerebral palsy in a large international study.

Objective: this study aimed to assess the effectiveness of Passive Ultrasonic Irrigation (PUI) with different so-lutions for calcium hydroxide (Ca(OH)2) removal. Ma-terials and method: forty-eight single-rooted mandibu-lar premolars were prepared and filled with Ca(OH)2. After 15 days, the specimens were randomly divided into four groups according to the method of removal of the intracanal medication (n=12). In Group 1, Ca(OH)2removal was performed through conventional irrigation with 2.5% NaOCl and 17% EDTA combined with the use of the 'master apical file' at working length. Groups 2 and 3 were treated in the same manner as Group 1, following the PUI with 2.5% NaOCl and 17% EDTA, and 2.5% NaOCl and 10% citric acid, respectively. Group 4 served as a control group and received no intracanal medication. The roots were longitudinally grooved and split in two halves. The half with the higher remaining amount was analyzed with a stereomicros-cope, and the percentage of surface area covered by the remaining Ca(OH)2 in relation to the total surface area and the surface area of each third of the root canal was calculated. The results were statistically analyzed with the Kruskal-Wallis Test and Mann-Whitney Test. Null hypothesis was set as 5%. Results: none of the groups tested showed similarity to the control group (P < 0.05)...
RESUMO
A 50-year-old man presented with a persistently warm left foot, which did not perspire. What initially seemed to be an innocent disorder turned out to be a retroperitoneal germ cell tumour situated at Liii-Liv. In most people this location is the site of the lumbar paravertebral ganglia (an important part of the sympathetic nervous system). The fact that these ganglia were affected by the tumour explained the autonomic dysfunction in this case. The patient received curative chemotherapy. Exploration of the symptoms with respect to the pathophysiology and anatomy of the autonomous nervous system might have led to an earlier diagnosis.
