: Minerals, though needed in small quantities, are essential to metabolic processes, and deficiencies can seriously threaten health, reproduction and survival. Despite this, few studies have measured mineral composition of wild primate foods and fewer have quantified mineral intake. Here we measured the concentration of nine minerals in 75 foods of diademed sifakas (Propithecus diadema; five groups) in habitats with varying levels of disturbance at Tsinjoarivo and estimated daily intakes using focal-animal feeding data and intake rates over one year...

BACKGROUND Postoperative conversion disorder is rare and has been reported. The diagnosis is usually made after all major organic causes have been ruled out. CASE REPORT We describe a case of a 13-year-old female who presented in the post-anesthesia care unit with acute-onset inspiratory stridor and unresponsiveness to verbal or painful stimuli after receiving a general anesthetic for upper endoscopy. Later in the post-anesthesia care unit, she presented with acute-onset right hemiplegia and sensory loss. She was first evaluated for causes of her stridor and unresponsiveness...

BACKGROUND: Literature in the application of gait training techniques in persons with traumatic brain injury is limited. Current techniques require of multiple staff and are physically demanding. The use of a robotic locomotor training may provide improved training capacity for this population. OBJECTIVE: To examine the impact of three different modes of locomotor therapy on gait velocity and spatiotemporal symmetry using: an end effector robot (G-EO™); a robotic exoskeleton (Lokomat®) and manual assisted partial-body weight supported treadmill training (PBWSTT) in participants with traumatic brain injury...

It is well-documented that neurological deficits after stroke can disrupt motor control processes that affect the smoothness of reaching movements. The smoothness of hand trajectories during multi-joint reaching depends on shoulder and elbow joint angular velocities and their successive derivatives as well as on the instantaneous arm configuration and its rate of change. Right-handed survivors of unilateral hemiparetic stroke and neurologically-intact control participants held the handle of a two-joint robot and made horizontal planar reaching movements...

BACKGROUND: Cerebral palsy (PCI) is the leading cause of disability in children. Botulinum toxin type A (TBA) is a treatment to improve the function and pattern in the gait, although with a few studies that quantify the improvement. METHODS: Quasi-experimental study was conducted from May 2010 to September 2011, in Integrated Rehabilitation Center, in 36 patients with spastic PCI. Was evaluated: functionality of travel by the scale of Koman, speed of the gait with tone scale of Ashworth and arches of passive mobility, were applied TBA and was sent to 10 sessions of physical therapy, with measurements taken before, the 1st and 4th month...

BACKGROUND: Crocin is considered to prevent oxidative stress-related diseases, such as ischemia and Alzheimer's. The aim of the present investigation was to evaluate the effects of crocin on motor behaviour and 6-OHDA-induced oxidative/nitrosative damage to the striatum in an experimental model of Parkinson's disease. METHODS: Left medial forebrain bundle was lesioned by microinjection of 6-OHDA (16μg in 0.2% ascorbate-saline). Crocin (30 and 60 mg/kg) was injected intraperitoneally three days before surgery until six weeks...

A 96-year-old woman developed hemiparesis 2 weeks after orthopedic surgery. Magnetic resonance imaging revealed multiple cerebral infarctions in the bilateral hemisphere. Transthoracic echocardiography revealed a mobile structure attached to the anterior mitral leaflet that protruded toward the left ventricular outflow tract. The structure was identified as an accessory mitral valve. Doppler echocardiography showed that there was no significant left ventricular outflow obstruction. This is a rare case of a silent accessory mitral valve that was detected after multiple cerebral infarctions...

Stroke can lead to motor impairments that can affect the body structure and restraint mobility. We hypothesize that brain lesions and their motor sequelae can distort the body schema, a sensorimotor map of body parts and elements in the peripersonal space through which human beings embody the reachable space and ready the body for forthcoming movements. Two main constructs have been identified in the embodiment mechanism: body-ownership, the sense that the body that one inhabits is his/her own, and agency, the sense that one can move and control his/her body...

The Gait Deviation Index (GDI) is a summary measure that provides a global picture of gait kinematic data. Since the ability to walk is critical for post-stroke patients, the aim of this study was to determine the reliability and Minimum Detectable Change (MDC) of the GDI in this patient population. Twenty post-stroke patients (11 males, 9 females; mean age, 55.2±9.9years) participated in this study. Patients presented with either right- (n=14) or left-sided (n=6) hemiparesis. Kinematic gait data were collected in two sessions (test and retest) that were 2 to 7days apart...

BACKGROUND Aspergillus terreus is an evolving opportunistic pathogen, and patients with A. terreus often have poor outcomes due to its intrinsic resistance to several systemic antifungal agents. Here we present a unique case of intracranial abscesses of A. terreus in a patient with recurrent angiosarcoma, complicated by development of tension pneumocephalus. CASE REPORT A 67-year old gentleman with history of scalp angiosarcoma with wide excision two years prior presented to the hospital for left arm clumsiness, altered mental status, and low-grade fever...

BACKGROUND: Hemiparetic stroke leads to structural and metabolic alterations of skeletal muscle tissue, thereby contributing to functional impairment associated with stroke. In situ metabolic processes at tissue level in skeletal muscle have not been investigated. We hypothesize that muscular metabolic capacity is limited after hemiparetic stroke, and that changes affect rather the paretic than non-paretic limb. METHODS: Nine male hemiparetic stroke survivors (age, 62±8years; BMI, 28±4kg/m(2); median stroke latency, 23months ranging from 7 to 34months poststroke) underwent dynamic in situ measurements of carbohydrate and lipid metabolism at fasting condition and during oral glucose tolerance testing, using bilateral microdialysis...

Brain abscess commonly occurs secondary to an adjacent infection (mostly in the middle ear or paranasal sinuses) or due to hematogenous spread from a distant infection or trauma. Pulmonary arteriovenous fistulas (AVFs) are abnormal direct communications between the pulmonary artery and vein. We present two cases of brain abscess associated with asymptomatic pulmonary AVF. A 65-year-old woman was admitted with a headache and cognitive impairment that aggravated 10 days prior. An magnetic resonance (MR) imaging revealed a brain abscess with severe edema in the right frontal lobe...

PREMISE OF THE STUDY: Loranthaceae, Santalaceae, and Viscaceae are the most diversified hemiparasitic families of Santalales in the Andes. Their partial inflorescences (PIs) vary from solitary flowers, or dichasia in most Santalales, to congested floral groups along articles in most Viscaceae. The atypical articled inflorescences in Phoradendreae (Viscaceae), a phylogenetic novelty restricted to this tribe, have been variously described as racemes, spikes, fascicles, or as intercalary inflorescences, but no developmental studies have been performed to compare them with the construction of PIs across Santalales...

BACKGROUND: Stroke survivors experience greater strength deficits during finger extension than finger flexion. Prior research indicates relatively little observed weakness is directly attributable to muscle atrophy. Changes in other muscle properties, however, may contribute to strength deficits. OBJECTIVES: This study measured muscle fiber conduction velocity (MFCV) in a finger flexor and extensor muscle to infer changes in muscle fiber-type after stroke. METHODS: Conduction velocity was measured using a linear EMG surface electrode array for both extensor digitorum communis and flexor digitorum superficialis in 12 stroke survivors with chronic hand hemiparesis and five control subjects...

Intracranial aspergillosis (ICA) is very rare in the immunocompetent individuals, usually misdiagnosed as a tumor or an abscess. A high index of clinical suspicion is required in patients who present with focal neurological deficits, headache, or seizures. We report the case of a 25-year-old immunocompetent female, who presented with a 15-month history of headache, seizures, left-sided proptosis and ophthalmoplegia, and right hemiparesis. Recovery from the symptoms and decrease in the lesion size seen on the radiological assessment were achieved through two decompressive craniotomies followed by prolonged combined systemic antifungal therapies...

Dyke-Davidoff-Masson syndrome (DDMS) is a rare, but important cause of drug-resistant seizures. Dyke-Davidoff-Masson syndrome is a constellation of clinical features that consists of hemiparesis, seizure, facial asymmetry, and intellectual disability with distinct neuroimaging features. A 27-year-old lady presented to us with drug-resistant epilepsy, hemiparesis, and intellectual disability that necessitated her withdrawal from school. Her brain magnetic resonance imaging (MRI) showed cerebral hemiatrophy, calvarial thickening, and hyperpneumatization of the frontal sinuses consistent with DDMS...

INTRODUCTION: Paretic upper limb in stroke patients has a significant impact on the quality of life. Modified Constraint Induced Movement Therapy (mCIMT) is one of the treatment options used for the improvement of the function of the paretic limb. AIM: To investigate the efficacy of four week duration mCIMT in the management of upper extremity weakness in hemiparetic patients due to stroke. MATERIALS AND METHODS: Prospective single blind, parallel randomized controlled trial in which 30 patients received conventional rehabilitation programme (control group) and 30 patients participated in a mCIMT programme in addition to the conventional rehabilitation programme (study group)...

We report the case of a 35-year-old woman who developed severe right-sided hemiplegia and hemisensory loss shortly after emergence from general anesthesia for a laparoscopic cholecystectomy. Her medical history was significant for migraine with aura and a family history of transient hemiparesis thought to be a result of a transient ischemic attack. The patient's deficits slowly resolved, and she was ultimately diagnosed with familial hemiplegic migraine after a negative workup for cerebrovascular accidents.

BACKGROUND: COL4A1 on chromosome 13q34 encodes the alpha 1 chain of type IV collagen, a component of basal membranes. It is expressed mainly in the brain, muscles, kidneys, and eyes. COL4A1 mutations can remain asymptomatic or cause devastating disease. Neonates and children may present with porencephaly, intracerebral hemorrhage, or hemiparesis, whereas adults tend to develop intracranial aneurysms or retinal arteriolar tortuosities. PATIENT DESCRIPTION: We describe a term infant with encephalomalacia, extensive intrauterine stroke and anterior segment dysgenesis with a de novo mutation in COL4A1...
