Hypertrophic olivary degeneration (HOD) is a rare trans-synaptic neuronal degeneration of the inferior olivary nucleus caused by an injury to the dentato-rubro-olivary connection, also known as Guillain-Mollaret triangle. It leads to hypertrophy of the affected nucleus rather than atrophy and is characterized by hyperintensity on T2-weighted images. Unilateral and bilateral cases are described. We present a case of a 70-year-old patient affected by a tumor inside the fourth ventricle who suffered from diplopia and right seventh cranial nerve palsy...

Various ocular and systemic reactions have been associated with insect sting. However, insect stings have been rarely reported to cause exotropia and diplopia. We encountered exotropia in a 6-year-old child with rhabdomyolysis of the left lower extremities caused by an insect sting. Exotropia and diplopia developed within 1 day after the sting and improved completely 1 week after the onset of symptoms. Clinicians should be aware of the potential for the development of exotropia in patients with insect stings, which requires careful follow-up...

Abducens nerve palsy (ANP) is commonly seen in patients with diabetes mellitus. The validity of acupuncture as a traditional Chinese medicine method in peripheral nerve repair is well established. However, its efficacy in randomized controlled trials remains unclear. Herein, we designed a protocol for a prospective, single-center, randomized controlled trial to investigate the effect of intraorbital electroacupuncture on diabetic ANP. We plan to recruit 60 patients with diabetic ANP, and randomly divide them into treatment and control groups...

BACKGROUND AND OBJECTIVES: Postoperative retinal folds are a rare complication of retinal detachment repair. Folds involving the macula may result in decreased vision, metamorphopsia, and diplopia. There is no consensus on whether symptomatic folds require additional surgery, as both spontaneous regression and permanent vision loss have been described. The authors present three cases of symptomatic macular folds that demonstrated spontaneous resolution and identify key OCT prognostic signs...

Introduction In case of cavernous sinus dural arteriovenous fistula (CSDAVF), transvenous embolization (TVE) of the cavernous sinus (CS) via the inferior petrosal sinus (IPS) is generally performed. However, various approach routes have been reported when the accessibility of the IPS is challenging. We herein report a case of CSDAVF treated by TVE with direct puncture of the facial vein. Case report A 70-year-old woman who suffered from tinnitus, chemosis, diplopia and bruit was referred to our hospital. Digital subtraction angiography (DSA) demonstrated CSDAVF...

Background Double lumen balloon catheters (DLBCs) are currently used in the treatment of intracranial aneurysms, especially when involving balloon or stent-assisted coiling. The existing DLBCs allow the delivery of self-expandable stents but do not offer the possibility to deploy flow-diverters. Despite the increasing use and success of flow-diverters, there have been numerous reports of procedural complications such as early in-stent thrombosis or delayed distal embolization. It seems that these complications can be avoided by correct stent positioning and adequate wall apposition, achieved either by manoeuvres with the microguidewire and/or microcatheter or by performing balloon angioplasty following an exchange guidewire manoeuvre...

Reversible acetylcholinesterase inhibitors are used as first-line treatment for myasthenia gravis. They improve symptoms by increasing concentration of acetylcholine at the neuromuscular junction and stimulating nicotinic receptors. Serious bradyarrhythmias can occur from muscarinic stimulation in heart, which in rare cases may progress to asystole. These patients can initially be managed with hyoscyamine, a muscarinic antagonist. Persistence of bradyarrhythmias even after hyoscyamine treatment may warrant pacemaker placement...
