BACKGROUND: Despite an increasing understanding of the pathophysiology of achalasia, the etiology of this esophageal motility disorder remains largely unknown. However, the occurrence of familial achalasia, its association with well-defined genetic syndromes, the candidate gene approach, and recent presentation of the first systematic genome-wide association study on achalasia suggest the involvement of genetic factors. METHODS: In this study we analyzed the frequency with which symptoms associated with esophageal function (swallowing difficulties, regurgitations, retrosternal cramps/pain, heartburn) occur in first-degree relatives of patients with achalasia to determine if screening is useful and justified against the background of early diagnosis in a genetically predisposed population...

PURPOSE OF REVIEW: Magnesium (Mg) imbalances are frequently overlooked. Hypermagnesemia usually occurs in preeclamptic women after Mg therapy or in end-stage renal disease patients, whereas hypomagnesemia is more common with a prevalence of up to 15% in the general population. Increasing evidence points toward a role for mild-to-moderate chronic hypomagnesemia in the pathogenesis of hypertension, type 2 diabetes mellitus, and metabolic syndrome. RECENT FINDINGS: The kidneys are the major regulator of total body Mg homeostasis...

Disorders of sleep and wakefulness occur in about 60-98% of patients with Parkinson's disease (PD). The majority of research on the scale and nature of the disorders was performed in patients treated with antiparkinsonian drugs, and, therefore, the true picture of sleep disorders was interfering with side effects of therapy. The spectrum of these disorders in PD patients is broad and includes insomnia, parasomnia and hypersomnia. The main symptoms of insomnia are difficulty in maintaining sleep, associated with nocturia, rapid eye movement (REM) sleep behavior disorder (RBD), night cramps, akinesia and tremor...

OBJECTIVE: Movement disorders are a rare manifestation of Moyamoya angiopathy (MMA). Data on prevalence and clinical presentation are warranted. Possible involuntary movements include focal motor seizures, tremor, limb-shaking transient ischemic attacks, choreiform and spastic or dystonic movement disorders. PATIENTS AND METHODS: We developed a questionnaire to systematically assess movement disorders in MMA. Patients' history of involuntary movements and their clinical presentation were assessed systematically by interview...

REVIEW
Susanna B Park, Matthew C Kiernan, Steve Vucic
Axonal excitability testing provides in vivo assessment of axonal ion channel function and membrane potential. Excitability techniques have provided insights into the pathophysiological mechanisms underlying the development of neurodegeneration and clinical features of amyotrophic lateral sclerosis (ALS) and related neuromuscular disorders. Specifically, abnormalities of Na(+) and K(+) conductances contribute to development of membrane hyperexcitability in ALS, thereby leading to symptom generation of muscle cramps and fasciculations, in addition to promoting a neurodegenerative cascade via Ca(2+)-mediated processes...

Hereditary neuropathy with liability to pressure palsies (HNPP) is a rare autosomal-dominant disorder that most commonly produces recurrent painless focal sensory and motor neuropathies often preceded by minor, mechanical stress, or minor trauma. Herein, we report 2 pediatric cases of HNPP with atypical presentations; isolated muscle cramping and toe walking. Electrophysiologic testing disclosed multifocal sensorimotor polyneuropathy with slowing of sensory conduction velocities in both cases, which prompted PMP 22 gene deletion testing...

Paroxysmal gluten-sensitive dyskinesia (previously termed canine epileptoid cramping syndrome) is a condition of Border terriers in which the leading manifestation is neurological. The authors describe a case they believe to represent the first report of a Border terrier with a combination of neurological signs, atopy, positive serological results for anti-transglutaminase 2 (TG2 IgA) and anti-gliadin (AGA IgG) antibodies, and signs suggestive of gastrointestinal disease with pathological changes in the gastrointestinal tract-seemingly responsive to a gluten-free diet...

BACKGROUND: Bleeding disorders (BD) occur in up to 50% of adolescents with heavy menstrual bleeding (HMB). This presents unique challenges to healthcare providers given the complexity of treating the condition and such complexity can result in difficulty with patients understanding basic information about their condition, limit communication with medical providers, and patient compliance. SPECIFIC AIMS: To use an electronic approach to enhance patient compliance with medications used to treat their HMB...

Lycopus lucidus Turcz has been used as a traditional phytomedicine for menstrual disorder, amenorrhea, menstrual cramps, inflammation and cardiovascular diseases. However, there is not enough information about identification and quantification for the chemical constituents of L. lucidus Turcz. In this work, a simple, rapid and sensitive UHPLC-Q-TOF-MS method was developed for characterization and identification of the phytochemical compositions in L. lucidus Turcz in negative ion mode. A total of 37 compounds, including 15 phenolic acids, 12 flavonoids, three triterpenoids and seven organic acids were tentatively characterized and identified by means of the retention time, accurate mass and characteristic fragment ions...

Primary dysmenorrhea (PDM), characterized by cramping pain in the lower abdomen, is a common gynecological disorder in women of child-bearing age. An increasing number of neuroimaging studies have emphasized that PDM is associated with functional and structural abnormalities in the regions related to the default mode network (DMN). Based on resting-state functional magnetic resonance imaging (fMRI), the aim of this study was to use amplitude of low-frequency fluctuation (ALFF) and functional connectivity (FC) to investigate changes of the intrinsic brain activity in the DMN in PDM...

BACKGROUND: Nocturnal leg cramps are painful, involuntary muscle contractions commonly seen in elderly. While mostly harmless, they can severely impair quality of life and often disrupt sleep. Adverse drug effects may be responsible for a fraction of nocturnal leg cramps but often go unrecognized, resulting in additional prescribing intended to deal with adverse effects that might be better addressed by reduction, substitution, or discontinuation of the offending agent. CASE PRESENTATION: An 87 year old female presented as outpatient in family medicine with nocturnal leg cramps which had been present for five years and increasingly burdened her quality of life...

Writers' cramp is a movement disorder with dystonic co-contraction of fingers and hand during writing and is part of the clinical spectrum of focal dystonias. Previous studies showed reduced striatal dopamine receptor D2 (DRD2) availability in dystonia. The expression of D2 receptors is modulated by a DRD2/ANKK1-Taq1A polymorphism (rs1800497). This study addresses the question of whether the DRD2/ANKK1-Taq1A polymorphism is a risk factor for writer's cramp. We determined the DRD2/ANKK1-Taq1A polymorphism 34 patients with writer's cramp compared to 67 age matched controls...

BACKGROUND: Mental rotation of body parts engages cortical-subcortical areas that are actually involved in the execution of a movement. Musicians' dystonia is a type of focal hand dystonia that is grouped together with writer's cramp under the rubric of "occupational dystonia", but it is unclear to which extent these two disorders share common pathophysiological mechanisms. Previous research has demonstrated patients with writer's cramp to have deficits in mental rotation of body parts...

PURPOSE OF REVIEW: This article provides a description on clinical features and pathophysiology of the main sleep disorders observed in Machado-Joseph disease (MJD). RECENT FINDINGS: Pathological studies have clearly demonstrated that degenerative process in MJD is widespread in the nervous system, and not restricted to the cerebellum. Nonmotor manifestations are frequent and may include pain, cramps, dysautonomia, cognitive deficits, psychiatric manifestations, olfactory deficits, fatigue, nutritional issues, and sleep disorders...

Sleep-related movement disorders should be differentiated from parasomnias, sleep-associated behavioral disorders, and epilepsy. Polysomnography (PSG) is the gold standard in evaluating such disorders. Periodic leg movement disorder during sleep (PLMS), hypnic jerks, bruxism, rhythmic movement disorder, restless legs syndrome, and nocturnal leg cramps have broadly been discussed in the literature. However, periodic arm movement disorder in sleep (PAMS) is a less-appreciated entity perhaps because arm surface electromyography is not an integral part of the standard polysomnography...

Abnormality of sensorimotor integration in the basal ganglia and cortex has been reported in the literature for patients with task-specific focal hand dystonia (FHD). In this study, we investigate the effect of manipulation of kinesthetic input in people living with writer's cramp disorder (a major form of FHD). For this purpose, severity of dystonia is studied for 11 participants while the symptoms of 7 participants have been tracked during 5 sessions of assessment and Botulinum toxin injection (BoNT-A) therapy (one of the current suggested therapies for dystonia)...

The Guillain-Barré syndrome (GBS) is one of the few neuropathies well known to the general public, in part because of its association with swine flu vaccinations in 1976. GBS has again reached the general public with its possible association with Zika virus. The virus, borne by infected Aedes aegypti mosquitos, is being linked to birth defects when pregnant women are bitten and infected. There are early reports also linking GBS to Zika infection, which could expose a wider range of infected people to the neuropathy...
