BACKGROUND: Oromandibular dystonia is a movement disorder that is characterized by involuntary masticatory and/or lingual muscle contracture. Jaw closing dystonia, the most common subtype of this condition, can cause trismus and is frequently misdiagnosed as temporomandibular joint disorder or masticatory muscle tendon-aponeurosis hyperplasia. MATERIALS AND METHODS: This report describes the long-term results of 18 patients with limited mouth opening (mean maximal mouth opening: 12...

Hyperkinetic movement disorders such as tremors are not uncommon in patients with multiple sclerosis (MS). The classical feature is intention tremor, whereas rest tremors appear not to occur. Treatment is mainly invasive, with options of Gamma Knife surgery, thalamotomy or deep brain stimulation depending on individual circumstances. Deep brain stimulation is the only option for patients who require a bilateral intervention. All treatment recommendations have only low evidence. Tremors can also be cured spontaneously by a subsequent strategic MS lesion...

During the "DBS Canada Day" symposium held in Toronto July 4-5, 2014, the scientific committee invited experts to share their knowledge regarding deep brain stimulation (DBS) management of movement disorders in three domains: (1) the programming algorithms, (2) the necessary team to run a neurosurgery program, and (3) the appropriate scales to better define in a more comprehensive fashion the effect of the brain surgery. Each presentation was followed by an open discussion, and this article reports on the conclusions of this meeting on these three questions...

The American College of Surgeons (ACS) National Surgical Quality Improvement Program (NSQIP) provides a rich database of North American surgical procedures and their complications. Yet no external source has validated the accuracy of the information within this database. Using records from the 2006 to 2013 NSQIP database, we used two methods to identify errors: (1) mismatches between the Current Procedural Terminology (CPT) code that was used to identify the surgical procedure, and the International Classification of Diseases (ICD-9) post-operative diagnosis: i...

BACKGROUND: We previously showed that the protein pattern of lenses removed in cataract surgery differs between patients with Parkinson's disease and age-matched controls. In this study, we identified the protein reduced in abundance in the 34- to 37-kDa gel band. METHODS: During cataract surgery (phacoemulsification), we collected the rinsing fluid and lens particles from the eyes of PD patients and controls. Residual lens fragments in the supernatant of 3 PD patients and aged-matched controls were studied for protein profiles using liquid chromatography-mass spectrometry and Western blots...

Glutaric aciduria type I (GA-I; synonym, glutaric acidemia type I) is a rare inherited metabolic disease caused by deficiency of glutaryl-CoA dehydrogenase located in the catabolic pathways of L-lysine, L-hydroxylysine, and L-tryptophan. The enzymatic defect results in elevated concentrations of glutaric acid, 3-hydroxyglutaric acid, glutaconic acid, and glutaryl carnitine in body tissues, which can be reliably detected by gas chromatography/mass spectrometry (organic acids) and tandem mass spectrometry (acylcarnitines)...

BACKGROUND: Posttraumatic tremor (PTT) is the most frequent movement disorder secondary to cranioencephalic trauma and can be persistent and disabling. OBJECTIVES: We review and assess the efficacy of deep brain stimulation (DBS) at the VIM/VOP/ZI (ventralis intermedius/ventrooralis posterior/zona incerta) complex level for the treatment of PTT. METHODS: During the period from 1999 to 2014, 5 patients diagnosed with PTT were selected who had experienced a major deterioration in their quality of life without improvement during medical treatment for more than 1 year...

BACKGROUND: Dystonia is a movement disorder with patterned, directional, and often sustained muscle contractions that produce abnormal postures or repetitive movements. Deep brain stimulation (DBS) of the globus pallidus internus (GPi) is an effective and safe treatment for medically refractory dystonia. However, recent studies reported gait problems, gait freezing and falls in patients treated with DBS. Because these symptoms may point to deficient gait initiation processes, we systematically assessed the anticipatory postural adjustments (APAs) prior to stepping in dystonia patients with GPi-DBS...

BACKGROUND: Dystonia is characterised by involuntary movements (twisting, writhing and jerking) and postures. Secondary dystonias are described as a heterogeneous group of disorders with both exogenous and endogenous causes. There is a growing body of literature on the effects of deep brain stimulation (DBS) surgery on the motor function in childhood secondary dystonias, however research on cognitive function after DBS is scarce. METHODS: Cognitive function was measured in a cohort of 40 children with secondary dystonia following DBS surgery using a retrospective repeated measures design...

In this Clinical practice guide, an analysis is made of the diagnosis and treatment of adult patients with constipation and abdominal discomfort, under the spectrum of irritable bowel syndrome and functional constipation. These have an important personal, health and social impact, affecting the quality of life of these patients. In irritable bowel syndrome with a predominance of constipation, this is the predominant change in bowel movements, with recurrent abdominal pain, bloating and frequent abdominal distension...

OBJECTIVE: With orbital floor fracture incidence rates increasing year by year, many patients require surgical treatment to improve diplopia, limitation of extraocular muscle movement (EOM), enophthalmos, and midface appearance. With the use of high-density polyethylene, titanium screws, titanium plate, and titanium mesh to repair an orbital floor fracture, enophthalmos and midfacial deformity correction procedures have made great progress. However, attenuating diplopia and the limitation of EOM are still difficult problems to prevent...

OBJECTIVE: The aim of this study was to evaluate the neurobehavioral safety of constant-current subthalamic deep brain stimulation and to compare the neuropsychological effects of stimulation versus electrode placement alone. METHODS: A total of 136 patients with Parkinson's disease underwent bilateral subthalamic device implantation in this randomized trial. Patients received stimulation either immediately after device implantation (n = 101; active stimulation) or beginning 3 months after surgery (n = 35; delayed activation control)...

OBJECTIVE: The most recent international consensus update on dystonia classification proposed a system based on 2 axes, clinical characteristics and aetiology. We aimed to apply this system to Children and Young People (CAYP) selected for movement disorder surgery, and determine if meaningful groupings of cases could be extracted. METHODS: The 2013 Consensus Committee classification system for dystonia was retrospectively applied to 145 CAYP with dystonic movement disorders...

BACKGROUND: Microelectrode recordings along preplanned trajectories are often used for accurate definition of the subthalamic nucleus (STN) borders during deep brain stimulation (DBS) surgery for Parkinson's disease. Usually, the demarcation of the STN borders is performed manually by a neurophysiologist. The exact detection of the borders is difficult, especially detecting the transition between the STN and the substantia nigra pars reticulata. Consequently, demarcation may be inaccurate, leading to suboptimal location of the DBS lead and inadequate clinical outcomes...

Proteus syndrome (PS) is a rare congenital hamartomatous disorder with multisystem involvement. PS shows highly clinical variability due to overgrowth of the affected areas, and several features can make anesthetic management challenging. Little is known about the airway problem associated with anesthesia in PS patients. An 11-year-old girl with PS was scheduled for ear surgery under general anesthesia. She had features complicating intubation including facial asymmetry and disproportion, abnormal teeth, limitation of neck movement due to torticollis, and thoracolumbar scoliosis...

BACKGROUND: Heterogeneous by the underlying pathobiology and clinical presentation, childhood onset dystonia is most frequently progressive, with related disability and limitations in functions of daily living. Consequently, there is an obvious need for efficient symptomatic therapies. METHODS AND RESULTS: Following lesional surgery to basal ganglia (BG) and thalamus, deep brain stimulation (DBS) is a more conservative and adjustable intervention to and validated for internal segment of the globus pallidus (GPi), highly efficient in treating isolated "primary" dystonia and associated symptoms such as subcortical myoclonus...

OBJECTIVE: Orthopedic disorders of IMC walking children associated with other disorders of posture and movement get progressively worse with growth causing major deformations that can impede walking from the age of 2 years. The treatments implemented by physiotherapy, botulinum toxin and multi-site surgery significantly improve the functional prognosis of these children. The goal is to evaluate the fate of children who have not benefited from multi-site surgeries that have benefited from physiotherapy, stretching casts botulinum toxin and tenotomy on one or two sites...

Drawing on and extending the Foucaultian philosophical framework that Jeffrey Bishop develops in his masterful book, The Anticipatory Corpse: Medicine, Power, and the Care of the Dying, we undertake a sociological analysis of the neurological procedure-deep brain stimulation (DBS)-which implants electrodes in the brain, powered by a pacemaker-like device, for the treatment of movement disorders. Following Bishop's work, we carry out this analysis through a two-fold strategy. First, we examine how a multidisciplinary team evaluates candidates for this implant at a major medical center...

INTRODUCTION: Deep brain stimulation (DBS) is an established therapy for movement disorders, and is under active investigation for other neurologic and psychiatric indications. While many studies describe outcomes and complications related to stimulation therapies, the majority of these are from large academic centers, and results may differ from those in general neurosurgical practice. METHODS: Using data from both the Centers for Medicare and Medicaid Services (CMS) and the National Surgical Quality Improvement Program (NSQIP), we identified all DBS procedures related to primary placement, revision, or removal of intracranial electrodes...
