#1
Antonio Carota, Julien Bogousslavsky
A right "minor hemisphere" does not exist as the right hemisphere is dominant for awareness (nosognosia), spatial attention, emotional regulation, facial and voice expressions, visual recognition, and topographical orientation. Without the right hemisphere, the world would be flat, deprived of general and spatial attentions, pointing preferentially to the right side of the space, lacking visual experiences and emotions, exhibiting diminished awareness of the self and environment. Clinical-related syndromes of the right hemisphere are unilateral spatial neglect, object and face visual agnosia, the anosognosia for hemiparesis and/or hemianopia, misidentification syndromes, mania, and other obsessions for the food and the body...

Multiple Sclerosis (MS) is an autoimmune disease in which lymphocytes target putative myelin antigens in the CNS, causing inflammation and neurodegeneration. Fingolimod (FTY720) is an immunosuppressive drug used as a second line therapy for relapsing forms of MS due to its safety profile and good response to treatment. Despite its safety, there are still concerns about the possibility of Fingolimod being linked to the development of opportunistic infections like disseminated varicella zoster infections and herpes simplex encephalitis...

Subacute sclerosing panencephalitis is a late complication of measles infection and develops usually 6 to 15 years after the primary measles infection. Fulminant subacute sclerosing panencephalitis is an infrequently encountered form wherein the disease rapidly progresses to death. A six-year old male child presented with fever, abnormal movements of the left side of body followed by weakness of the left side of the body, and involuntary abnormal movements of right upper and lower limbs. On examination, he was drowsy and was unable to communicate...

BACKGROUND: Constraint-induced movement therapy (CIMT) is increasingly recognized as an effective therapy for children with hemiparesis. However, the effectiveness of CIMT outside the standard rehabilitation protocol in clinical settings is less known. The aim of this systematic review was to investigate the effectiveness of CIMT conducted at home or in a group. METHODS: We searched CINAHL, PubMed and ScienceDirect in August 2017 to select articles of studies investigating the impact of CIMT performed at home and in a group on affected upper-limb ability, occupational performance, and quality of life of children...

Parasitic plants can serve as critical intermediaries between their hosts and other organisms; however these relationships are not well understood. To investigate the relative importance of plant traits in such interactions, we studied the role of the root hemiparasite, Castilleja levisecta (Orobanchaceae), as a mediator of interactions between the host plants it parasitizes and the lepidopteran herbivore Euphydryas editha (Nymphalidae), whose caterpillars feed on Castilleja and sequester iridoid glycosides from it...

OBJECTIVE: Given the presence of execution deficits after stroke, it is difficult to determine if patients with stroke have deficits in motor skill learning with the paretic arm. Here, we controlled for execution deficits while testing practice effects of the paretic arm on motor skill learning, long-term retention, and corticospinal excitability. METHODS: Ten patients with unilateral stroke and ten age-matched controls practiced a kinematic arm skill for two days and returned for retention testing one-day and one-month post-practice...

This study aimed to identify and qualify grasp-types used by patients with stroke and determine the clinical parameters that could explain the use of each grasp. Thirty-eight patients with chronic stroke-related hemiparesis and a range of motor and functional capacities (17 females and 21 males, aged 25-78), and 10 healthy subjects were included. Four objects were used (tissue packet, teaspoon, bottle and tennis ball). Participants were instructed to "grasp the object as if you are going to use it". Three trials were video-recorded for each object...

A 20-year-old man presented with consciousness disturbance and hemiparesis, and computed tomography demonstrated subarachnoid and intracerebral hemorrhage. Angiography on admission demonstrated a slight irregularity of the middle cerebral artery (MCA) branch. Angiography on the 12th day showed a suspicious lesion at M3 of the left MCA. Angiography performed 24 days after the onset disclosed an aneurysm at M3. The aneurysm was trapped and resected after superficial temporal artery-MCA bypass. Pathological examinations revealed that this distal aneurysm was a pseudoaneurysm without vascular components in its dome...

Case: The standard treatment for acute subdural hematoma (ASDH) is large craniotomy; decompressive craniectomy may also be carried out, if needed, to prevent secondary brain damage. Recently, an endoscopic procedure for elderly patients with ASDH was carried out and reported; its safety and effectiveness were emphasized because of minimal invasiveness. We report a young case and discuss its difficulties and tips.A 31-year-old man was found to be in a state of general convulsion. At the time of admission, we observed severe consciousness disturbance, anisocoria, and left hemiparesis...

Spasticity is a common problem in patients with stroke that contributes to motor dysfunction. However, the pathophysiological mechanisms underlying spasticity are not fully understood. The purpose of the present study was to explain the relationship between features of spinal neural circuits assessed using electrophysiological techniques and the clinical manifestations of stroke. The participants were 71 patients with chronic hemiparetic stroke. To assess spinal neural circuits, Hmax/Mmax of the forearm flexor muscles and reciprocal inhibition (RI) between forearm extensor and flexor muscles with the H reflex conditioning-test paradigm were measured...

Transcranial direct current stimulation (tDCS) is used in a variety of disorders after stroke including upper limb motor dysfunctions, hemispatial neglect, aphasia, and apraxia, and its effectiveness has been demonstrated. Although gait ability is important for daily living, there were few reports of the use of tDCS to improve balance and gait ability. The supplementary motor area (SMA) was reported to play a potentially important role in balance recovery after stroke. We aimed to investigate the effect of combined therapy body weight-supported treadmill training (BWSTT) and tDCS on gait function recovery of stroke patients...

Introduction: Each year 7 million people die of stroke worldwide; most deaths are caused by chest infections. Patients with acute stroke have impaired voluntary cough flow, associated with increased risk of chest infections. Reduced functional residual capacity (FRC) could lead to impaired cough flow. We therefore compared FRC in acute hemiparetic stroke patients and controls and explored its relationship with volume inspired before cough and voluntary cough peak flow. Methods: 21 patients within 2 weeks of first-ever middle cerebral artery territory (MCA) infarct (mean (SD) age 68 (11) years, 10 females) and 30 controls (58 (11) years, 15 females) underwent FRC and voluntary cough testing (cough inspired volume and peak flow) while semirecumbent...

A 73-year-old man was admitted for cardiac tamponade by oozing type left ventricular free wall rupture associated with acute myocardial infarction. Transthoracic echocardiography demonstrated moderate pericardial effusion and the presence of pseudoaneurysm within posterior wall. He went into shock with a systolic blood pressure of 60 mmHg. After introducing percutaneous cardiopulmonary support and intraaortic balloon pump, the sutureless repair was performed immediately. After having rehabilitation for right-sided hemiparesis, an elective pseudoaneurysm repair was planned...
