Bladder hyperreflexia is a common non-motor feature of Parkinson's disease. We now report on the contractility of the isolated primate detrusor strips devoid of nerve input and show that following MPTP, the amplitude and frequency of spontaneous contraction was increased. These responses were unaffected by dopamine D1 and D2 receptor agonists A77636 and ropinirole respectively. Contractions by exogenous carbachol, histamine or ATP were similar and no differences in the magnitude of noradrenaline-induced relaxation were seen in detrusor strip obtained from normal and MPTP-treated common marmosets (Callithrix jacchus)...

Omega-3 polyunsaturated fatty acids (PUFAs), such as Docosaexaenoic Acid (DHA) and Eicosapentaenoic Acid (EPA), mediate neuroactive effects in experimental models of traumatic peripheral nerve and spinal cord injury. Cellular mechanisms of PUFAs include reduced neuroinflammation and oxidative stress, enhanced neurotrophic support, and activation of cell survival pathways. Bioactive omega-9 monounsaturated fatty acids, such as Oleic Acid (OA) and 2-Hydroxy Oleic Acid (2-OHOA), also show therapeutic effects in neurotrauma models...

Twelve individuals of consanguineous Bedouin kindred presented with autosomal recessive progressive spastic paraplegia evident as of age 0-24 months, with spasticity of lower limbs, hyperreflexia, toe walking and equinus deformity. Kyphoscolisois was evident in older patients. Most had atrophy of the lateral aspects of the tongue and few had intellectual disability. Nerve conduction velocity, electromyography and head and spinal cord magnetic resonance imaging were normal in tested subjects. Muscle biopsy showed occasional central nuclei and fiber size variability with small angular fibers...

Cramp-fasciculation syndrome (CFS) is a rare muscle hyperexcitability syndrome that presents with muscle cramps, fasciculations, and stiffness, as well as pain, fatigue, anxiety, hyperreflexia, and paresthesias. Although familial cases have been reported, a genetic etiology has not yet been identified. We performed whole-exome sequencing followed by validation and cosegregation analyses on a father-son pair with CFS. Both subjects manifested other hypersensitivity-hyperexcitability symptoms, including asthma, gastroesophageal reflux, migraine, restless legs syndrome, tremor, cold hyperalgesia, and cardiac conduction defects...

ZC4H2 is involved in human brain development, and, if mutated, can be responsible for a rare X-linked disorder, originally presented in literature as Wieacker-Wolff syndrome and Miles-Carpenter syndrome. In males, severe intellectual disability is associated with variable symptoms of central and peripheral nervous system involvement, such as spasticity, hyperreflexia, muscle weakness, and arthrogryposis. Female carriers are usually described as asymptomatic or only mildly affected. Here, we report on a girl carrying a de novo deletion of ZC4H2 detected by array-CGH analysis...

Peroxisome biogenesis factor 10 (PEX10) is involved in the import of peroxisomal matrix proteins, and the mutation of this gene causes 3 subtypes of peroxisome biogenesis disorders, namely Zellweger syndrome (severe), neonatal adrenoleukodystrophy (moderate) and an ataxic form (mild). Here, we report 3 siblings of the ataxic form with cerebellar ataxia, mild mental retardation, and 3 additional characteristic features: mydriasis, hyperreflexia and involuntary head movement. All 3 siblings are compound heterozygous for a previously reported mutation, c...

In contrast to other levels of upper disc spaces, the Luschka joints are usually absent at the C7/T1 disc space. Therefore, it has been reported that the C7/T1 disc herniation is prone to herniate laterally rather than centrally. In this manuscript, we describe an extremely rare central-type disc herniation at the C7/T1 level presented with myelopathy. A 76-year-old man presented with a 20-day history of progressive gait disturbance. Physical examination revealed bilateral lower extremity hyperreflexia and mild foot numbness with no upper extremity motor weakness or sensory disturbance...

The term 'serotonin syndrome' describes a constellation of symptoms caused by serotonergic overstimulation. Its characteristic clinical presentation consists of encephalopathy, neuromuscular signs and autonomic hyperactivity. After removal of the offending agent, the clinical course is usually self-limited but can occasionally lead to severe symptoms. We report the case of a 68-year-old woman who presented emergently with encephalopathy. Home medications included paroxetine and dextroamphetamine/amphetamine...

Several genetic disorders caused by defective nucleotide excision repair that affect the skin and the nervous system have been described, including Xeroderma Pigmentosum (XP), De Sanctis-Cacchione syndrome (DSC), Cockayne syndrome, and Trichothiodystrophy. Cutaneous photosensitivity with an increased risk of skin malignancy is a common feature of these disorders, but clinical manifestations commonly overlap these syndromes. Several genes have been found to be altered in these pathologies, but we lack more genotype-phenotype correlations in order to make an accurate diagnosis...

Hashimoto's Encephalopathy (HE) is a rare form of autoimmune encephalopathy associated with Hashimoto's thyroiditis in which patients experience cognitive impairment and various neurologic symptoms. We present a case of a young female that presented to the emergency department with urinary retention, and was ultimately diagnosed with HE. Examination was significant for direction-changing and vertical nystagmus (direction-changing nystagmus describes a phenomenon where the fast beat changes with the direction of gaze), hyperreflexia, clonus, and Babinski and Hoffman's reflexes (all upper motor neuron (UMN) signs)...

Toshi, a 14-year-old Japanese boy, had uncontrolled asthma after relocating from Japan with his family 1 year ago. In Japan, he was diagnosed with moderate, persistent asthma, which was controlled with salmeterol and albuterol on an as needed basis. Since moving to the United States, Toshi complained of frequent dyspnea.Initially, he was seen by a Japanese physician who prescribed 200 mg of fluticasone 3 times a day and albuterol nebulization as needed. When Toshi came to the Pediatric Primary Care Clinic, he reported using his nebulizer up to 25 times daily...

In this report, the patient was pre-diagnosed as meningioma before surgery, which turned out to be meningeal melanocytoma. Hence, we will discuss the interpretation of imaging and neurological statuses that may help avoid this problem. A 45-year-old man had increasing pain around the neck 14 months prior to admission. His cervical spine MR imaging revealed a space-occupying, contrast-enhancing mass within the dura at the level of C1. The neurologic examination revealed that the patient had left-sided lower extremity weakness of 4+, decreased sensation on the right side, and hyperreflexia in both legs...

BACKGROUND: Ossification of the posterior longitudinal ligament (OPLL) can cause myelopathy that is often managed surgically. Knowledge of predictors of surgical outcomes can provide decision support to surgeons. The aims of this study were to investigate the relationships between preoperative physical signs and postoperative functional outcomes in patients with OPLL and to clarify whether physical signs could predict functional outcomes. METHODS: Fifty-five patients with OPLL who had undergone cervical laminoplasty were included in this study...

A 64-year-old man presented with blackish pigmentation of skin and tongue for more than 2 years that did not improve with local remedies. He had no history of comorbid medical or surgical illnesses. General examination showed severe hyperpigmentation of skin and mucosa and also showed anaemia. Systemic examination was unremarkable except for Romberg sign and mild hyperreflexia. Adrenal insufficiency was ruled out by normal cortisol levels and haemogram showed macrocytosis with hypersegmented neutrophils suggestive of severe vitamin B12 deficiency which confirmed by low serum B12 levels...

A 29-year-old woman developed progressive dysarthria and coordination problems from the age of 15. Examination showed dysarthria, facial dystonia, bibrachial dystonia, hyperreflexia, ataxia, and emotional incontinence. Downward supranuclear gaze palsy was prominent with a "Round the Houses" sign. Magnetic resonance imaging of the brain and medulla, electroneurography, and cerebrospinal fluid were normal. A computed tomography scan showed hepatosplenomegaly. This combination of progressive neurological symptoms together with hepatosplenomegaly was suggestive of inborn error of metabolism...

Although liver transplant for decompensated cirrhosis secondary to Wilson disease is well accepted, the use of transplant for patients with severe neurologic manifestations of this condition remains controversial, and these can be perceived as a contraindication. Here, we describe a 45-year-old woman who presented with an incidental hepatocellular carcinoma at the time of transplant. The patient had severe neurologic manifestations of Wilson disease pretransplant, including dysarthria, hyperreflexia, asymmetrical ataxia, tremor, bradyphrenia, and shuffling gait...

INTRODUCTION: Overactive Bladder (OAB) accounts for 40-70% cases of incontinence. The etiology is unknown though detrusor instability is found in urodynamic evaluation of almost all cases. Detrusor instability or hyperreflexia can be inhibited by direct inhibition of impulses in the pre-ganglionic afferent neuron or by inhibition of bladder pre-ganglionic neurons of the efferent limb of micturition reflex. Transcutaneous Electrical Nerve Stimulation (TENS) is based on the gate control theory of abolishing the local micturition reflex arc...
