Parkinson's Disease.

Med Clin North Am 2019 Mar 3;103(2):337-350. Epub 2018 Dec 3.

Department of Neurology, University of Maryland School of Medicine, 110 South Paca Street, 3rd Floor, Baltimore, MD 21201, USA.

The diagnosis of Parkinson disease (PD) is based on the presence of bradykinesia and either resting tremor or rigidity and there should be no features from the history or examination to suggest an alternative cause of parkinsonism. In addition to the motor manifestations of PD, there is a long list of nonmotor symptoms, several of which occur before motor signs and are considered "prodromal" PD. These are classified as neuropsychiatric, autonomic, sleep, and sensory. Read More

The Pioneering and Unknown Stereotactic Approach of Roeder and Orthner from Göttingen. Part II: Long-Term Outcome and Postmortem Analysis of Bilateral Pallidotomy in the Pre-Levodopa Era.

Stereotact Funct Neurosurg 2018 16;96(6):353-363. Epub 2019 Jan 16.

Department of Neurology, Inselspital, University Hospital Bern, Bern, Switzerland.

Before the advent of levodopa, pallidotomy was initially the most effective treatment for Parkinson disease, but it was soon superseded by thalamotomy. It is widely unknown that, similar to Leksell, 2 neurologists from Göttingen, Orthner and Roeder, perpetuated pallidotomy against the mainstream of their time. Postmortem studies demonstrated that true posterior and ventral pallidoansotomy sparing the overwhelming mass of the pallidum was accomplished. Read More

The Future of Surgical Treatments for Parkinson's Disease.

J Parkinsons Dis 2018 ;8(s1):S79-S83

Department of Neurological Surgery, University of Toronto, Toronto, ON, Canada.

The surgical treatment of Parkinson's disease has made significant progress over the past 70 years; however, its scope of effectiveness remains limited to motor symptoms like bradykinesia, rigidity, tremor and medication-induced dyskinesias. The field of surgery initially developed from lesioning procedures and then transitioned largely to deep brain stimulation due to its properties of adaptability and reversibility. Interestingly, there has been a renewed interest in lesioning procedures secondary to the introduction of focused ultrasound, a non-invasive technology. Read More

Robot-assisted tremor control for performance enhancement of retinal microsurgeons.

Br J Ophthalmol 2018 Dec 20. Epub 2018 Dec 20.

Department of Ophthalmology, Johns Hopkins University School of Medicine, Baltimore, Maryland, USA.

Pars plana vitrectomy is a challenging, minimally invasive microsurgical procedure due to its intrinsic manoeuvres and physiological limits that constrain human capability. An important human limitation is physiological hand tremor, which can significantly increase the risk of iatrogenic retinal damage resulting from unintentional manoeuvres that affect anatomical and functional surgical outcomes. The limitations imposed by normal physiological tremor are more evident and challenging during 'micron-scale' manoeuvres such as epiretinal membrane and internal limiting membrane peeling, and delicate procedures requiring coordinated bimanual surgery such as tractional retinal detachment repair.

Tremor Other Hyperkinet Mov (N Y) 2018 27;8:566. Epub 2018 Jul 27.

Barrow Neurological Institute, Phoenix, AZ, USA.

Background: Orthostatic tremor (OT) is a hyperkinetic movement disorder characterized by rapid tremor in the lower extremities or trunk upon standing.

Case Report: We report two patients presenting with OT, whose symptoms improved markedly following asleep bilateral thalamic deep brain stimulation (DBS) surgery.

Discussion: Medically refractory OT can respond favorably to asleep bilateral DBS surgery similar to awake surgery, and may have the advantages of less psychological trauma to the patient, shorter procedure times, and less exposure to anesthesia. Read More

Parkinsonian signs in patients with cervical dystonia treated with pallidal deep brain stimulation.

Brain 2018 Oct;141(10):3023-3034

Sobell Department of Motor Neuroscience, UCL Institute of Neurology, National Hospital for Neurology and Neurosurgery, London, UK.

Pallidal deep brain stimulation is an established treatment in patients with dystonia. However, evidence from case series or uncontrolled studies suggests that it may lead in some patients to specific parkinsonian symptoms such as freezing of gait, micrographia, and bradykinesia. We investigated parkinsonian signs using the Movement Disorder Society Unified Parkinson's Disease Rating Scale motor score by means of observer-blinded video ratings in a group of 29 patients treated with pallidal stimulation and a non-surgical control group of 22 patients, both with predominant cervical dystonia.

Patient-specific anatomical model for deep brain stimulation based on 7 Tesla MRI.

PLoS One 2018 22;13(8):e0201469. Epub 2018 Aug 22.

Center for Magnetic Resonance Research, Department of Radiology, University of Minnesota, Minneapolis, MN, United States of America.

Objective: Deep brain stimulation (DBS) requires accurate localization of the anatomical target structure, and the precise placement of the DBS electrode within it. Ultra-high field 7 Tesla (T) MR images can be utilized to create patient-specific anatomical 3D models of the subthalamic nuclei (STN) to enhance pre-surgical DBS targeting as well as post-surgical visualization of the DBS lead position and orientation. We validated the accuracy of the 7T imaging-based patient-specific model of the STN and measured the variability of the location and dimensions across movement disorder patients. Read More

Current surgical treatments for Parkinson's disease and potential therapeutic targets.

Neural Regen Res 2018 Aug;13(8):1342-1345

Division of Neurosurgery, Toronto Western Hospital, Department of Surgery, University of Toronto, Toronto, Canada.

Currently, the most common surgical treatment for Parkinson's disease is deep brain stimulation (DBS). This treatment strategy is typically reserved for bradykinesia, rigidity and tremor in patients who no longer respond to medication in a predictable manner or who suffer medication-induced dyskinesias. In addition to DBS, ablative procedures like radiofrequency, radiosurgery and focused ultrasound are also utilized for select tremor symptoms. Read More

Robotic versus laparoscopic gastrectomy with lymph node dissection for gastric cancer: study protocol for a randomized controlled trial.

Trials 2018 Jul 31;19(1):409. Epub 2018 Jul 31.

Second Department of Surgery, School of Medicine, Wakayama Medical University, 811-1, Kimiidera, Wakayama, 641-8510, Japan.

Background: Laparoscopic gastrectomy (LG) has several benefits as a treatment of gastric cancer (GC), including reduced pain, early recovery of intestinal function, and shorter hospital stay. LG still has several drawbacks, however, including limited range of movement, amplification of hand tremors, and inconvenient surgical positioning. Around the peripancreatic area, laparoscopic lymph node dissection, therefore, remains challenging; postoperative pancreatic fistula occurs in around 4-7% of patients undergoing LG. Read More

A minimally invasive neurostimulation method for controlling abnormal synchronisation in the neuronal activity.

PLoS Comput Biol 2018 07 19;14(7):e1006296. Epub 2018 Jul 19.

naXys, Namur Institute for Complex Systems, University of Namur, Namur, Belgium.

Many collective phenomena in Nature emerge from the -partial- synchronisation of the units comprising a system. In the case of the brain, this self-organised process allows groups of neurons to fire in highly intricate partially synchronised patterns and eventually lead to high level cognitive outputs and control over the human body. However, when the synchronisation patterns are altered and hypersynchronisation occurs, undesirable effects can occur. Read More

Decisions about deep brain stimulation therapy in Parkinson's disease.

Arq Neuropsiquiatr 2018 Jun;76(6):411-420

University of Toronto, Toronto Western Hospital, Movement Disorders Centre, University Health Network, Toronto, Canada.

Parkinson's disease can be treated surgically in patients who present with motor complications such as fluctuations and dyskinesias, or medically-refractory disabling tremor. In this review, a group of specialists formulated suggestions for a preoperative evaluation protocol after reviewing the literature published up to October 2017. In this protocol, eligibility and ineligibility criteria for surgical treatment were suggested, as well as procedures that should be carried out before the multidisciplinary therapeutic decisions.
