"Diabetic striatopathy" is characterized by dyskinesias with basal ganglia hyperintensities on neuroimaging. It is usually reported in elderly females with hyperglycemic hyperosmolar state and rare in patients with diabetic ketoacidosis. Here, we report two young males with diabetic ketoacidosis presenting as striatopathy, along with review of literature.

BACKGROUND: Although the dopamine precursor L-3, 4-dihydroxyphenylalanine ( l -dopa) remains the gold standard pharmacological therapy for patients with Parkinson's disease (PD), long-term treatment with this drug has been known to result in several adverse effects, including l -dopa-induced dyskinesia (LID). Recently, our group reported that KD5040, a modified herbal remedy, had neuroprotective effects in both in vitro and in vivo models of PD. Thus, the present study investigated whether KD5040 would have synergistic effects with l -dopa and antidyskinetic effects caused by l -dopa as well...

Functional dyspepsia (FD) is a constellation of epigastric symptoms originating in the gastroduodenal region without organic and metabolic cause. However, similar confounding symptoms can also appear in patients with gallbladder (GB) dyskinesia. Therefore, symptoms of GB dyskinesia may be mistaken for FD. We aimed to identify GB dyskinesia as a cause of FD symptoms compatible with the Rome IV criteria and the need for an evaluation of GB function in patients with FD symptoms.We investigated information of patients with FD symptoms who underwent a quantitative Tc-diisoproyl iminodiacetic acid cholescintigraphy (DISIDA scan) through electronic medical records, and GB dyskinesia was judged to be the cause of the FD symptoms if the symptoms disappeared as GB function normalized on the follow-up DISIA scan in patient with decreased GB function on the initial DISIDA scan...

Anti-N-methyl-d-aspartate receptor (anti-NMDA-R) encephalitis is an autoimmune disorder that was first described by Dr Vitaliani in 2005. In 2007, Dalmau et al. found anti-NMDA-R antibody expressed both in the hippocampus and prefrontal nerve cell membrane, finally proposing the diagnosis of autoimmune anti-NMDA-R encephalitis. Most of the patients are female (91%), with ages ranging from 4 to 76 years. The average age is 23 years, a birth peak age, although anti-NMDA-R encephalitis is rare during pregnancy...

OBJECTIVE: Parkinson's disease (PD) is currently incurable, however proper treatment can ease the symptoms and significantly improve the quality of life of patients. Since PD is a chronic disease, its efficient monitoring and management is very important. The objective of this paper was to investigate the feasibility of using the features and methodology of a spirography application, originally designed to detect early Parkinson's disease (PD) motoric symptoms, for automatically assessing motor symptoms of advanced PD patients experiencing motor fluctuations...

We report a 16-year-old man with disorders of tetrahydrobiopterin metabolism due to dihydropteridine reductase (DHPR) deficiency. He revealed moderate mental retardation, parkinsonism, and spastic paralysis with levodopa and 5-hydroxytryptophan (5-HTP) supplementation from the age of 2 months. Brain MRI showed high intensity areas in bilateral frontal and posterior deep white matter on fluid-attenuated inversion recovery (FLAIR). Coronal FLAIR image showed a high signal in bilateral pyramidal tracts. Single photon computed tomography (SPECT) imaging of the dopamine transporter was normal...

REVIEW
Lynne Marie Schofield, Alistair Duff, Cathy Brennan
Primary Ciliary Dyskinesia (PCD) is a rare inherited disease with impaired mucociliary clearance. Airway clearance techniques (ACTs) are commonly recommended for patients with PCD to facilitate mucus clearance, despite a lack of evidence in this group. Current physiotherapy practice in PCD is based on evidence extrapolated from the field of Cystic Fibrosis (CF). This paper focuses on the available evidence and outlines challenges in extrapolating evidence between the conditions for best clinical practice.

INTRODUCTION: Glucose transporter type 1 deficiency syndrome (GLUT1-DS) is a rare metabolic encephalopathy with a wide variation of clinical phenotypes. Familial variants are often milder than de novo cases, and may therefore remain undiagnosed. The aim of this study was to characterize the clinical course of GLUT1-DS in a four-generation Norwegian family where the oldest generations had never received any treatment. METHOD: Through interviews and clinical investigations, we characterized a family of 26 members, where 11 members had symptoms strongly suggesting GLUT1-DS...

PURPOSE: When levodopa (L-DOPA) is administered orally, it is eliminated from the body very quickly resulting in a series of sharp fluctuations in its blood concentrations. These frequent changes in blood levels are considered to be responsible for the development of late motor complications and dyskinesias, which are troubling clinical and treatment issues in Parkinson's disease. Transdermal drug delivery is a patient-compliant method for delivering therapeutics into the systemic circulation in a continuous and controlled manner...

BACKGROUND. We report the 12-month clinical and imaging data on the effects of bilateral delivery of the glutamic acid decarboxylase gene into the subthalamic nuclei (STN) of advanced Parkinson's disease (PD) patients. METHODS. 45 PD patients were enrolled in a 6-month double-blind randomized trial of bilateral AAV2-GAD delivery into the STN compared with sham surgery and were followed for 12 months in open-label fashion. Subjects were assessed with clinical outcome measures and (18)F-fluorodeoxyglucose (FDG) PET imaging...

The vesicular monoamine transporter 2 (VMAT2) is an integral presynaptic protein that regulates the packaging and subsequent release of dopamine and other monoamines from neuronal vesicles into the synapse. Valbenazine (NBI-98854), a novel compound that selectively inhibits VMAT2, is being developed for the treatment of tardive dyskinesia. Valbenazine is converted to two significant circulating metabolites in vivo, namely, (+)-α-dihydrotetrabenazine (R,R,R-DHTBZ) and a mono-oxy metabolite, NBI-136110. Radioligand binding studies were conducted to assess and compare valbenazine, tetrabenazine and their respective metabolites in their abilities to selectively and potently inhibit [(3)H]-DHTBZ binding to VMAT2 in rat striatal, rat forebrain, and human platelet homogenates...

BACKGROUND: Primary ciliary dyskinesia (PCD) and cystic fibrosis (CF) are increasingly compared. There are no chest magnetic resonance imaging (MRI) comparative studies of PCD and CF. We assessed clinical, functional, microbiological and MRI findings in PCD and mild CF patients in order to evaluate different expression of lung disease. METHODS: Twenty PCD (15.1 years) and 20 CF subjects with mild respiratory impairment (16 years, 70% with pancreatic insufficiency) underwent MRI, spirometry, and sputum cultures when clinically stable...

Secondary paroxysmal dyskinesias (SPDs) are short, episodic, and recurrent movement disorders, classically related to multiple sclerosis (MS). Carbamazepine is effective, but with risk of adverse reactions. We identified 7 patients with SPD among 457 MS patients (1.53%). SPD occurred in face ( n = 1), leg ( n = 2), or arm +leg ( n = 4) several times during the day. Magnetic resonance imaging (MRI) showed new or enhancing lesions in thalamus ( n = 1), mesencephalic tegmentum ( n = 1), and cerebellar peduncles ( n = 5)...

In April 2015, a 20-year-old woman with multiple sclerosis (MS) presented with acute onset of repetitive abnormal postures and choreatic movements of the right arm, precipitated by voluntary movements (online video 1 and 2). Brain magnetic resonance imaging (MRI) showed a new active MS lesion involving the basal ganglia on the left side (Figure 1(a)). Intravenous steroid treatment resulted in rapid regression of this paroxysmal kinesigenic dyskinesia (PKD)-like hyperkinetic movement disorder. The patient became asymptomatic within 3 months...

Reserpine is an irreversible inhibitor of vesicular monoamine transporter-2 (VMAT2) used to study Parkinson's disease (PD) and screening for antiparkinsonian treatments in rodents. Recently, the repeated treatment with a low-dose of reserpine was proposed as a progressive model of PD. Rats under this treatment show progressive catalepsy behavior, oral movements and spontaneous motor activity decrement. In parallel, compared to Wistar rats, spontaneously hypertensive rats (SHR) are resistant to acute reserpine-induced oral dyskinesia...

OBJECTIVES: Tardive dyskinesia (TD) is a movement disorder that may develop as a side effect of antipsychotic medication. The aetiology underlying TD is unclear, but a number of mechanisms have been proposed. METHODS: We investigated single-nucleotide polymorphisms (SNPs) in the genes coding for neuregulin-1 and erbB-4 receptor in our sample of 153 European schizophrenia patients for possible association with TD. RESULTS: We found the ERBB4 rs839523 CC genotype to be associated with risk for TD occurrence and increased severity as measured by the Abnormal Involuntary Movement Scale (AIMS) (P = ...
