BACKGROUND: Focal task-specific dystonia is a form of isolated focal dystonia that occurs during the performance of a specific skilled motor task. The occurrence of oromandibular dystonia (OMD) specifically in association with the recitation of Quranic verses have been rarely reported in the literature, in non-native Arabic-speaking patients. This case series describe a rare type of focal task-specific dystonia that occurs exclusively by reciting Quran in native Arabic-speaking patients, which has never been reported, to the best of our knowledge...

Schwartz-Jampel Syndrome (SJS) type-1 (OMIM; #255800), a rare cause of skeletal dysplasia, is characterized by myotonic myopathy, chondrodystrophy, short stature, facial and eye abnormalities. SJS Type-1 develops due to variations in the HSPG2 gene which produces the "perlecan" molecule, one of the main proteoglycans of the basement membrane. A 6-year-old girl presented with short stature, a mask face, shrunken lips, narrow palpebral opening due to blepharospasm, stiffness of facial muscles, micrognathia, overlapping teeth, a short neck, and a bell-shaped thorax due to myotonic myopathy...

A 26-y-old, male, captive Humboldt penguin ( Spheniscus humboldti ) was euthanized following a 3.5-mo history of weakened elimination mechanics, recurrent tenesmus, intermittent hemorrhagic droppings, and a cloacal mass. Blepharospasm, of unknown cause, of the right eye was present for ~3 mo before euthanasia. Autopsy revealed a cloacal adenocarcinoma with localized coelomic carcinomatosis and distant metastases to the liver and lungs. On histopathology, a 2.6 × 1.2 × 0...

OBJECTIVE: To analyze mental disorders in blepharospasm (BS) before and after botulinum therapy (BT). MATERIAL AND METHODS: We examined 25 patients with BS (9 men and 16 women), aged 50 to 85 years (mean 64.1±18.5), with BS (main study group). The control group consisted of 20 healthy individuals (7 men and 13 women, mean age 63.5±8.5). Patients were examined before and after BT (after 3 weeks) using a diagnostic structured interview Mini International Neuropsychiatric Interview, GAD-7, PHQ-9, fear of negative assessment (short version) and The Liebowitz Social Anxiety Scale (LSAS)...

OBJECTIVES: The objective of the study was to evaluate whether a twice-daily instillation of 0.45% preservative-free ketorolac tromethamine (FKT) or 0.4% benzalkonium chloride-preserved ketorolac tromethamine (BACKT), every 12 h for 30 days may affect tear film parameters and the meibography in healthy dogs. Additionally, we assessed whether the same treatments irritated the ocular surface, affected goblet cell density (GCD), and the levels of oxidative stress biomarkers (OSB) in the conjunctiva of the same dogs...

This report details a rare case where a patient simultaneously suffered from Sjogren's syndrome (SS) and Meige's syndrome (MS). SS, an autoimmune disorder, and MS, a rare neurological condition characterized by involuntary eyelid closure, presented in a 73-year-old male. The patient had been experiencing dry eye symptoms for the past 5 years, with the onset of eyelid spasms and tetanic eye closure occurring 3 years ago. Traditional treatments, including subthalamic nucleus deep brain stimulation, provided only temporary relief...

BACKGROUND: Deep brain stimulation of the subthalamic nucleus (STN-DBS) is an effective treatment for patients with motor symptoms of Parkinson disease but can be complicated by disabling blepharospasm and apraxia of eyelid opening (ALO). Currently, there is no clear consensus on optimal management, and addressing these issues is further hindered by systemic morbidity and resistance to treatments. We aim to describe the different phenotypes of these eyelid movement disorders, to report our management approach and patient responses to treatment...

BACKGROUND: There are several widely used clinical rating scales for documenting the severity and distribution of various types of dystonia. OBJECTIVES: The goal of this study was to evaluate the performance of the most commonly used scales in a large group of adults with the most common types of isolated dystonia. METHODS: Global Dystonia Rating Scale (GDRS) and the Burke-Fahn-Marsden Dystonia Rating Scale (BFM) scores were obtained for 3067 participants...

PURPOSE: To assess the change of interleukin-6 (IL-6) levels in tears and ocular clinical parameters in corneal ulcer patients with moderate-to-severe infection after adjunctive therapy with platelet-rich fibrin (PRF) lysate-eyedrops compared with autologous serum eyedrops. MATERIALS AND METHODS: This study was a randomized double-blind controlled trial, which compared two groups of patients at Dr. Sardjito Hospital, Yogyakarta. A total of 42 patients (42 eyes) were divided into the control group (21 patients) and the intervention group (21 patients)...

BACKGROUND: Genetic factors have been implicated in the pathogenesis of blepharospasm (BSP), a dystonia characterized by excessive blinking and involuntary eyelid closure. Previous research identified a co-segregating deleterious TOR2A variant (GRCh38/hg38, NC_000009.12: g.127733410G>A, NM_001085347.3:c.568C>T, p. Arg190Cys) in three subjects with BSP and three carriers within a multi-generation pedigree. Other TOR2A variants have been reported in patients with dystonia. METHODS: Sanger sequencing was used to screen a cohort of 307 subjects with isolated BSP or BSP-plus dystonia affecting additional anatomical segments (BSP+)...

PURPOSE: To describe a simple cryosurgical technique for treating canine distichiasis, its success rate and any associated complications. METHODS: Clinical records from canine patients undergoing treatment for distichiasis using a specific cryotherapy technique were retrospectively reviewed. The technique employed a triple freeze-thaw cycle via a transconjunctivally applied, liquid nitrogen-cooled, 2-mm diameter closed cryoprobe. RESULTS: The cryotherapy technique was employed in 125 dogs with distichiasis over a period of 13 years, with 109 (87%) bilaterally and 16 (13%) unilaterally affected, totaling 234 eyes...

Deployment of the tear gas agent 2-chlorobenzalmalononitrile (CS) for riot control has significantly increased in recent years. The effects of CS have been believed to be transient and benign. However, CS induces severe pain, blepharospasm, lachrymation, airway obstruction, and skin blisters, and with frequent injuries and hospitalizations have been reported following exposure. We have identified the sensory neuronal ion channel, transient receptor potential ankyrin 1 (TRPA1), as a key CS target resulting in acute irritation and pain, and also as a mediator of neurogenic inflammation...

OBJECTIVE: Primary blepharospasm (BSP) is a clinically heterogeneous disease that manifests not only as spasmodic closure of the eyelids but also sometimes with apraxia of eyelid opening (AEO). This cross-sectional study aimed to investigate differences in the neural mechanisms of isolated BSP and BSP-associated AEO subtypes, which may reveal the pathophysiology underlying different phenotypes. METHODS: A total of 29 patients manifested as isolated BSP, 17 patients manifested as BSP associated with AEO, and 28 healthy controls underwent resting-state functional near-infrared spectroscopy (fNIRS)...
