Dystonia is a clinically and genetically heterogeneous disorder genetic cause often difficult to elucidate. This the first study use whole genome sequencing (WGS) investigate dystonia in large sample of affected individuals.WGS was performed on 111 probands with heterogenous phenotypes. We analysis for coding non-coding variants, copy number variants (CNVs), structural (SVs). assessed an association between 10 known risk variants.A diagnosis obtained 11.7% (13/111) individuals. found that...

Some constituents of snake venom have been found to display a variety biological activities. The antibacterial property venom, in particular, has gathered increasing scientific interest due antibiotic resistance. In the present study, king cobra was screened against three strains Staphylococcus aureus [including methicillin-resistant (MRSA)], other species gram-positive bacteria and six gram-negative bacteria. King active all 12 tested, most effective spp. (S. S. epidermidis). Subsequently,...

There are increasing reports of myasthenia gravis (MG) following oncological treatment with immune checkpoint inhibitors (ICIs).A 66-year-old man stage 3A lung adenocarcinoma was treated second weekly infusions durvalumab, a programmed cell death ligand-1 inhibitor, at dose 10 mg/kg. After the fourth infusion, he developed diplopia, dyspnoea and constitutional symptoms including headache, weakness anorexia. 1 month later, dysphagia dysphonia. Examination showed proximal limb fatigability. An...

An 18-year-old male presented with new-onset focal to bilateral tonic-clonic seizures 5 days after receiving the first dose of COVID-19 vaccine. 3 later, an identical seizure occurred lasting 1 min, leading acute presentation hospital. In hospital, patient was loaded intravenous phenytoin and started on levetiracetam no further recurrence. CT venogram scalp EEG were unremarkable. MRI brain revealed generalised atrophy mild hippocampal atrophy. The maintained 500 mg twice daily advised...

Motor neuron disease (MND) is a neurodegenerative disorder leading to functional decline and death. Multidisciplinary MND clinics provide an integrated approach management facilitate discussion on advanced care directives (ACDs). The study objectives are analyse (1) the prevalence of ACD in our clinic, (2) relationship between patient demographics (3) decision-making variables such as NIV, PEG, hospital admissions location death.Using clinic records, all patients who attended Liverpool...

T2 relaxation times (T2 times) are different between resting and exercised muscles of healthy subjects with muscle pathology. However, studies specifically focusing on neck lacking. Furthermore, normative not well defined methodology used to analyse in is robust. We analysed key explored factors affecting variability muscles. 20 were recruited. Two circular regions interest (ROIs) drawn two mutually exclusive within weighted images values averaged. ROI measurements performed by a...

<h3>Objectives</h3> T2 relaxation times (T2RT) of muscles increase with physical exercise, however T2RT has not been studied in dystonic are a state constant activity. Major involved cervical dystonia (CD) include splenius capitis, semispinalis levator scapulae, sternocleidomastoid and trapezius which also prime targets for botulinum toxin treatment. This study analysed the T2RTs key neck CD, compared them normal subjects. <h3>Methods</h3> 23 CD subjects underwent MRI clinical assessment...
