Treatment with albumin-hydroxyoleic acid complex restores sensorimotor function in rats with spinal cord injury: Efficacy and gene expression regulat…
2017
Sensorimotor dysfunction following incomplete spinal cord injury (SCI) is often characterized by paralysis, spasticity and pain. Previously, we showed that intrathecal (i.t.) administration of the albumin-oleic acid (A-OA) complex in rats with SCI produced partial improvement of these symptoms and that oral 2-hydroxyoleic acid (HOA, a non-hydrolyzable OA analogue), was efficacious in the modulation and treatment of nociception and pain-related anxiety, respectively. Here we observed that intrathecal treatment with the complex albumin-HOA (A-HOA) every 3 days following T9 spinal contusion injury improved locomotor function assessed with the Rotarod and inhibited TA noxious reflex activity in…

Post-traumatic lipoma of the parotid gland: case report
2008
The incidence of lipoma among parotid tumours ranges from 0.6% to 4.4%, with most series reporting an incidence of 1%. The most common origin of these tumours, in the parotid gland, is from the superficial lobe and, only rarely, from the deep lobe. Lipomas, upon clinical history, are found to be most frequently related to an episode of trauma. Computed Tomography scan and Magnetic Resonance Imaging can lead to a pre-operative diagnosis of lipoma. The case is described of lipoma of the superficial lobe of the parotid gland.
Unilateral laryngeal and hypoglossal paralysis (Tapia's syndrome) in a patient with an inflammatory pseudotumor of the neck
2012
Tapia’s syndrome (TS) is a rare condition thought tobe causedby njury to the extracranial course of both recurrent laryngeal branch f the vagal nerve and hypoglossal nerve. First described in 1904, t occurs with unilateral paralysis of the vocal cord and tongue, ith normal function of the soft palate. Commonly reported causes re direct trauma, neurofibromatosis of X and XII nerves, carotid rtery dissection involving the ascending pharyngeal artery, and isplacement of endotracheal tube during general anesthesia [1].
Retrospective review of L3 myelomeningocele in three age groups: should posterolateral iliopsoas transfer still be indicated to stabilize the hip?
2005
The data from 58 hips in 29 myelodysplastic children with L3 paralysis has been reviewed retrospectively. Posterolateral transfer of the iliopsoas (Sharrard technique) was performed on all hips to correct muscle imbalance between 1975 and 1992. The average length of follow-up was 21 years. Preoperatively, 58.6% of the hips were either subluxated or dislocated (these were surgically reduced at the same stage). Radiological assessment revealed that 91.4% of the hips were stable at preschool age and 84.5% in adolescence. Of the patients 86% were functional walkers at preschool age and 75.8% in adolescence. Downward transitions in seven patients were related to the presence of scoliosis, spasti…
Cortico-bulbar fibers to orofacial muscles: recordings with enoral surface electrodes.
1997
A new recording technique was developed to eliminate current problems on recording transcranial evoked facial muscle responses. A fork-shaped device equipped with 2 pairs of Ag/AgCl-electrodes was inserted enorally at the buccinator muscle level. Advantages offered by this method comprise clearly defined negative deflection of the compound muscle action potential, lack of relevant volume conduction from adjacent muscles, reliability of amplitude criteria, absence of interfering stimulus artifacts, easy achievement of preactivation, and noninvasive recording by surface electrodes. In 43 healthy subjects transcranial magnetic stimulation evoked contralateral responses at a mean latency and me…
Diaphragmatic paralysis following minor cervical trauma.
2007
Two asthmatic patients developed unilateral diaphragmatic paralysis from phrenic nerve injury, in one case following cervical chiropractic manipulation and in the other after a motorcycle accident. Both presented with increased dyspnea and orthopnea. Diagnosis, severity, and level of the lesion were established by neurophysiological methods, which are preferred to chest radiography and diaphragmatic ultrasonography. In spite of only partial electrophysiological recovery of the nerve, both patients were asymptomatic 1 year later.
Successful application of preimplantation genetic diagnosis for hypokalaemic periodic paralysis.
2009
Hypokalaemic periodic paralysis is a rare dominant inherited disease where a person suffers sudden falls of circulating potassium concentrations, producing muscle weakness and sometimes severe paralysis. Attacks can occur as frequently as several times a day or once in a year. The age of onset is usually adolescence but symptoms can appear as early as 10 years of age. Muscle weakness can compromise vital functions such as breathing or swallowing and heart arrhythmias are also frequent during attacks. Preimplantation genetic diagnosis, an early form of prenatal diagnosis for couples at risk of transmitting inherited diseases, was used to prevent the transmission of this disease. Six polymorp…
Reanimation of the Paralyzed Human Larynx With an Implantable Electrical Stimulation Device
2003
Objectives/Hypothesis Electrical stimulation of the posterior cricoarytenoid muscle, when paced with inspiration, offers a physiological approach to restore ventilation in bilateral laryngeal paralysis without any of the disadvantages associated with conventional treatment. Study Design A prospective study of six patients. Methods The patients were successfully implanted with an Itrel II stimulator (Medtronic, Inc). In postoperative sessions, stimulated vocal fold abduction, patient ventilation, and voice were assessed and compared with preoperative values. Results The optimum stimulus paradigm was a 1- to 2-second train of 1-millisecond pulses delivered at a frequency of 30 to 40 Hz and am…
