The Italian Dystonia Registry is a multicenter data collection system that will prospectively assess the phenomenology and natural history of adult-onset dystonia and will serve as a basis for future etiological, pathophysiological and therapeutic studies. In the first 6 months of activity, 20 movement disorders Italian centres have adhered to the registry and 664 patients have been recruited. Baseline historical information from this cohort provides the first general overview of adult-onset dystonia in Italy...

Pontine tegmental cap dysplasia is a rare hindbrain malformation syndrome with a hypoplastic pons, a tissue protrusion into the fourth ventricle, and cranial nerve dysfunction. We here report clinical, imaging, and genetic findings of the first extremely low-birth-weight preterm infant with pontine tegmental cap dysplasia born at 25 weeks of gestation and provide an overview of 29 sporadic cases. A prenatally diagnosed hypoplastic and rostrally shifted cerebellum was indicative of a hindbrain defect and later identified as an early sign of pontine tegmental cap dysplasia in our patient...

Forty years ago, C.D. Marsden proposed that blepharospasm should be considered a form of adult-onset focal dystonia. In the present paper, we provide a comprehensive overview of the findings regarding blepharospasm reported in the past 40 years. Although prolonged spasms of the orbicularis oculi muscles remain the clinical hallmark of blepharospasm, patients with blepharospasm may be characterized by various types of involuntary activation of periocular muscles. In addition to motor features, blepharospasm patients may also have nonmotor manifestations, including psychiatric, mild cognitive, and sensory disturbances...

Botulinum toxin is a polypeptide protoxin synthesized by Clostridium botulinum that results in localized reduction of muscle activity by inhibiting acetylcholine release at the neuromuscular junction. In 2004, the US Food and Drug Administration approved its application in the treatment of various medical conditions, such as facial wrinkles, strabismus, cervical dystonia, blepharospasm, and hyperhidrosis. Later, its application extended to improving dental esthetics and gummy smile. It was found to be a safe and effective alternative to medical therapy to treat various head and neck disorders that have a neurologic component...

Botulinum toxin is recognised as the gold standard for the treatment of essential blepharospasm and hemifacial spasm, which is similar in effect in synkinesis after facial nerve palsy. The injection intervals can be adjusted according to the patients' needs and be shortened for up to six weeks in cases of eyelid cramping. Newer indications for the use of botulinum toxin in ophthalmology include eyelid retraction in Graves' disease, induction of protective ptosis and treatment of crocodile tears syndrome after facial nerve palsy...

Sulfur mustard (SM) is a strong blistering, highly reactive, lipophilic chemical war agent that causes injury in different organs including the skin, eyes and respiratory tract. The Eyes are especially susceptible to the consequences of SM poisoning because of the aqueous and mucosal nature of conjunctiva and cornea. DNA alkylation and depletion of glutathione, are the most important mechanisms of SM action in the eye injuries. Acute clinical symptoms are including decrease in visual acuity, dryness, photophobia, blepharospasm, conjunctivitis and complaints of foreign body sensation and soreness that gradually progress to severe ocular pain...

Botulinum neurotoxin (BoNT) is the first biological toxin used in the treatment of ophthalmic diseases and to decrease skin wrinkles as an aesthetic agent. When used appropriately, it weakens the force of muscular contraction and/or inhibits glandular secretion. The most common areas for botulinum toxin treatment are the upper face, including the glabella, forehead, brows, and lateral canthal lines, or crow's feet. By relaxing the muscles causing wrinkles, non-permanent results may be achieved with its use...

OBJECTIVE: To describe improvement in blepharospasm with apraclonidine. BACKGROUND: Blepharospasm is a focal dystonia involving chiefly the orbicularis oculi and periocular muscles resulting in involuntary sustained eyelid closure. Botulinum toxin injection is the mainstay of treatment with meaningful improvement in over 85% of patients, but the effects often wear off within 3-4months. Apraclonidine is an alpha-2 adrenergic receptor agonist, which causes contraction of superior tarsal (Müller) muscle which may improve blepharospasm-related eyelid closure...

'Meige's syndrome' is a type of cranial dystonia characterized by blepharospasm and oromandibular dystonia and can be associated with complex movement of lower facial muscles, mouth, jaw, tongue, pharyngeal and cervical muscles. Frequently, blepharospasm is the earliest clinical manifestation, which spreads over a period of time to involve other cranial and extra-cranial muscles. Common characteristics of this syndrome are well known, but their variety is wide. Different eponyms such as "Breughel syndrome", "Wood syndrome", "Blepharospasm plus", "Segmental cranial dystonia" and "Segmental cranio-cervical dystonia" have been used to describe this entity with numerous anatomical variations...

OBJECTIVE: Benign Essential Blepharospasm (BEB) and hemifacial spasm (HFS) are the most common hyperkinetic movement disorders of facial muscles. Although similar in clinical presentation different pathophysiological mechanisms are assumed. Botulinum Neurotoxin (BoNT) is a standard evidence-based treatment for both conditions. In this study we aimed to assess grey matter microstructural differences between these two groups of patients and compared them with healthy controls. In patients we furthermore tracked the longitudinal morphometric changes associated with BoNT therapy...

BACKGROUND: Cervical dystonias have a variable presentation and underlying etiology, but collectively represent the most common form of focal dystonia. There are a number of known genetic forms of dystonia (DYT1-27); however the heterogeneity of disease presentation does not always make it easy to categorize the disease by phenotype-genotype comparison. CASE PRESENTATION: In this report, we describe a 53-year-old female who presented initially with hand tremor following a total hip arthroplasty...

Blepharospasm may be accompanied by eyelid opening apraxia (EOA) reducing the efficacy of botulinum toxin (BT) therapy. The frontalis suspension operation (FSO) is then the only effective treatment option available. We want to report the first long-term results with FSO. We studied 15 patients with blepharospasm and EAO unresponsive to BT therapy (9 females, 6 males, age 61.9 ± 11.5 years). FSO was performed by applying 2 polytetrafluoroethylene threads (PTFE, Gore-Tex(®)) per eye connecting the frontalis muscle to the upper eye lid...

Globe luxation is a painful and potentially vision-threatening condition in which the globe becomes trapped behind the eyelids requiring physician intervention in the emergency department or eye clinic. On presentation, the patient typically complains of an inability to close their eye, severe foreign body sensation, decreased vision, and significant eye pain. Although most visual symptoms are reversible and primarily result from exposure keratopathy, optic nerve damage, and permanent vision loss can occur from repeat or prolonged episodes of globe luxation...
