Case Reports
Myasthenic crisis following iodinated contrast material (iohexol) aspiration: a case report.
The number of contrast media-related procedures is ever increasing due to the widespread availability of theoretically safe, low osmolar iodinated contrast material. Although intravenously administered contrast is known to precipitate myasthenic crisis, oral contrast aspiration as a causative factor is not yet documented as such. A 48-year-old Sinhalese man diagnosed as having myasthenia gravis, was evaluated for progressive dysphagia with an upper gastrointestinal contrast study. ⋯ Treatment with intravenous immunoglobulin, high-dose steroids, and broad-spectrum intravenously administered antibiotics led to an uneventful recovery, although the latter part of the clinical course was complicated with total left lung collapse. Myasthenic crisis can be precipitated by various factors and a successful recovery requires mechanical respiratory support with immunomodulatory and steroid therapy. This is the first reported case that describes the development of myasthenic crisis following iohexol-associated aspiration pneumonitis.

Young-onset sporadic Creutzfeldt-Jakob disease with atypical phenotypic features: a case report.
Sporadic Creutzfeldt-Jakob disease, with a mean survival of 6 months, is duly considered among the most fatal neurological disorders. Rapidly progressive dementia with multi-axial involvement of the nervous system is the known presentation. Although, the peak age at onset is between sixth and eighth decades, cases of young-onset sporadic Creutzfeldt-Jakob disease have also been reported in the literature. Interestingly, these young-onset cases were reported to have some features distinct from their older age group counterparts, such as slower progression as well as longer duration of illness, dominance of psychiatric manifestations at the onset, and relatively less prevalence of radiological and electroencephalographic abnormalities. ⋯ Our patient represents an atypical clinical situation as she is much younger than the usual presentation of Creutzfeldt-Jakob disease and it progressed far too rapidly. Cognitive decline came late in the temporal sequence of clinical events; rather, the onset was dominated by features consistent with cerebellar ataxia and basal ganglia involvement. The presence of magnetic resonance imaging abnormality and electroencephalography changes are other rare findings in young-onset sporadic Creutzfeldt-Jakob disease.

Case Reports
Peripheral and central nervous system involvement in a patient with primary Sjögren's syndrome: a case report.
Primary Sjögren's syndrome is the second most common rheumatological disorder after rheumatoid arthritis. It typically presents as xerophthalmia and xerostomia in postmenopausal women. Involvement of the central nervous system has been recognized, although its pathogenesis and characteristics are poorly understood. Central nervous system complications are a diagnostic challenge and emphasize the need for systematic screening of patients with new peripheral and central neurological symptoms. ⋯ Even though exocrinopathy is the hallmark of Sjögren's syndrome, systemic symptoms are observed in one-third of patients. There is an urgent need to better characterize the mechanisms underlying different disease phenotypes and to perform randomized controlled trials in order to provide tailored and evidence-based treatment for primary Sjögren's syndrome.

Takotsubo cardiomyopathy is characterized by chest symptoms, electrocardiographic changes, and new regional wall motion abnormality in the apical segment of the left ventricle in the absence of obstructive coronary artery disease. Particularly, apical ballooning is broadly recognized as the classic form of takotsubo cardiomyopathy. Although the prognosis of most patients with takotsubo cardiomyopathy is generally favorable, complications associated with the morphological features of transient apical ballooning are not uncommon. ⋯ The presented cases indicated that important complications, such as intraventricular thrombus and severe mitral regurgitation, are associated with takotsubo cardiomyopathy in the acute phase. Because these complications are risk factors for developing a thromboembolic event or heart failure and/or pulmonary edema, timely and accurate identification of these complications is critical to achieving optimal clinical outcomes in patients with takotsubo cardiomyopathy.
