Rupture of supra-aortic neck arteries due to lesions caused by tracheal tubes
1984
Haemorrhages from the common carotid or innominate artery caused by tracheal tubes are rare but dramatic complications of head and neck surgery. Patients with metal tracheostomy cannulas or patients in the phase of wound healing after radical tumour resections of the pharynx and larynx run a greater risk. Following extensive tumour resections and radiation of the upper respiratory and digestive tracts in 680 patients, acute bleeding of the larger neck arteries occurred in 18 patients. In four of these cases, fistulae developed in the innominate or common carotid artery. These ruptures were caused by both plastic and metal tracheal tubes.
In vivo ultrasound real-time motion of the cervical spine during intubation under manual in-line stabilization: a comparison of intubation methods
2007
Background and objectiveIn emergency trauma situations, manual in-line stabilization of the cervical spine is recommended to reduce cervical spine movement during intubation. The aim of this study was to compare the effect of manual in-line stabilization during different intubation techniques on three-dimensional cervical spine movements and times to intubation.MethodsForty-eight subjects without any history of trauma, inflammatory or degenerative disorder of the cervical spine were randomly grouped, regardless of gender or age. All underwent elective surgery under general anaesthesia. Under manual in-line stabilization, laryngeal intubation with Macintosh laryngoscope, intubating laryngeal…
Long-Term Functional Outcome after Unilateral Cordectomy
2010
<i>Purpose of the Study:</i> Our aim was to longitudinally analyze the vocal outcome after endoscopic CO<sub>2</sub> laser resection of early glottic carcinoma. <i>Procedures:</i> Sixteen patients treated with laser surgery for T1 or T2 tumors of the vocal cords received voice therapy and were examined 1, 2, 3, 4.5, 6 and 12 months postoperatively. Besides videolaryngostroboscopy, each examination included history, phonetogram of the speaking and the singing voice, language-specific hoarseness diagram and a questionnaire (Voice Handicap Index 12 in German). <i>Results:</i> Objective parameters demonstrated a broad variability with a slight ten…
Preparedness for landing after a self-initiated fall.
2012
A startling auditory stimulus (SAS) causes a faster execution of voluntary actions when applied together with the imperative signal in reaction time tasks (the StartReact effect). However, speeding up reaction time may not be the best strategy in all tasks. After a self-initiated fall, the program for landing has to be time-locked to foot contact to avoid damage, and therefore advanced execution of the program would not be convenient. We examined the effects of SAS on the landing motor program in 8 healthy subjects that were requested to let themselves fall from platforms either 50 or 80 cm high at the perception of a visual imperative signal and land on specific targets. In trials at rand…
Abnormal facilitatory mechanisms in motor cortex of migraine with aura
2010
Experimental evidence suggests impairment of inhibitory intracortical circuits in migraine, while not much is known about activity of facilitatory intracortical circuits. In the present work we evaluated the effects of high frequency-repetitive transcranial magnetic stimulation (hf-rTMS) on the activity of facilitatory circuits of motor cortex in 18 patients affected by migraine with aura and 18 healthy subjects. Trains of 10 stimuli were applied to the motor cortex at 5-Hz frequency with recording of the EMG traces from the contralateral abductor pollicis brevis muscle (APB). Two intensities of stimulation (110% and 130% of resting motor threshold) were used in order to explore whether mot…
Effects of kinematics constraints on hand trajectory during whole-body lifting tasks
2000
Trajectories of the hands and whole-body center of mass were studied during whole-body lifting tasks. The movements of different parts of the body were monitored with the ELITE system. Subjects were instructed to lift to shoulder height an object placed at one of two distances (5-45 cm) before them on the floor. The lifts were performed both with and without kinematics constraints (i.e. to produce a straight hand trajectory while lifting, and to lift without any instructions, respectively). Hand trajectories were roughly straight when performed under the constrained condition, but curved when performed without instruction. Hand velocity curves showed bell-shaped profiles. In both groups, bo…
Maternal anxiety following delivery, early infant temperament and mother's confidence in caregiving.
2015
AbstractA mother’s emotional state is a well-known environmental factor that relates to the development of infant temperament. However, some relevant issues have not yet been fully explored. The current study examines the influence of determined maternal, contextual and perinatal variables on infant temperament and the mother’s confidence in caregiving during the first weeks of life. A prospective study was carried out in three-hundred and seventeen newborns and their mothers. Perinatal and socio-demographic variables were recorded. The mother’s anxiety and mood were measured in the first days after childbirth and again at 8 weeks. Infant temperament and the mother’s confidence in caregivin…
Prediction of complexity and complications of laparoscopic liver surgery: The comparison of the Halls‐score to the IWATE‐score in 100 consecutive lap…
2020
BACKGROUND The development of laparoscopic liver surgery is slower than in other disciplines. Two different scoring systems have been proposed to estimate difficulty of laparoscopic liver resections (LLR) preoperatively. The aim of this analysis was to compare these two scores in an independent patient cohort regarding the predictability of morbidity. METHODS All LLRs performed between 01/2011 until 01/2019 were identified from our prospective institutional database. Patient characteristics as well as intra- and postoperative data were analyzed. Postoperative complications were graded according to Dindo-Clavien classification. Difficulty of LLR was classified using IWATE- and Halls-score. R…
Quality of life during the first year after partial laryngectomy: Longitudinal study
2018
This prospective study was conducted to assess changes in quality of life (QOL) of patients who undergo a partial laryngectomy.The European Organisation for Research and Treatment of Cancer Quality of Life Questionnaires Core and Head and Neck (EORTC-QLQ-C30, QLQ-HN35) were used preprocedure (n = 218), 1 week (n = 159), 3 months (n = 122), and 1 year after partial laryngectomy (n = 88). Changes over time were analyzed with the Wilcoxon signed rank test and the Holm-Bonferroni method, and interpreted regarding clinical relevance.Most subscales worsened 1 week postprocedure, but many recovered to baseline level after 1 year. Dyspnea and cognitive functioning deteriorated over time, with worst…
Analysis of visually guided eye movements in subjects after whiplash injury
2011
Abstract Objective The aims of present research were to analyze the visually guided eye movements of subjects suffering from the consequences of whiplash injury and the possibility to differentiate patients from feigning subject. We analyzed the role of video-nystagmography for clinical and forensic aspects. Methods It was a prospective case–control study. Detailed history was taken and patients were thoroughly investigated. Smooth pursuit and saccadic eye movements were assessed in 33 patients affected by imbalance following a whiplash injury. A control group of 20 subjects was also evaluated. All tests were executed in neutral neck position and after left and right trunk rotation. Results…
