Intracranial atherosclerotic disease (ICAD) is a major cause of ischemic stroke worldwide and represents a significant health problem. The pathogenesis and natural history of ICAD are poorly understood, and rigorous treatment paradigms do not exist as they do for extracranial atherosclerosis. Currently, the best treatment for ICAD remains aspirin therapy, but many patients who are placed on aspirin continue to experience recurrent strokes. As microsurgical and endovascular techniques continue to evolve, the role of extracranial to intracranial bypass operations and stenting are increasingly being reconsidered. We performed a PubMed review of the English literature with a particular focus on treatment options for ICAD and present evidence-based data for the role of surgery and stenting in ICAD against medical therapy alone.

An accurate cancer diagnosis is critical as it can direct the use of site-directed, and potentially more effective, treatment options for specific types of cancer. A differential or uncertain diagnosis could prevent cancer patients from receiving optimal treatment, thus affecting their overall prognosis. Advances in molecular technology have led to the development of molecular cancer classifiers that can direct or confirm the diagnosis of metastatic cancers which would otherwise be considered uncertain or unknown. This case report describes the role of molecular diagnostics in the evaluation of a patient with a large pancreatic mass and a history of breast cancer. Results from a 92-gene molecular profiling assay (CancerTYPE ID®) predicted that this new mass was breast cancer. This diagnosis allowed for effective treatment and complete response in this patient.

History Of

Patients with subglottic hemangioma present with biphasic stridor during infancy. The natural history of this lesion is characterized by progressive airway obstruction during the proliferative phase of the lesion, followed by resolution of symptoms during the subsequent involutive phase. Although this is a benign neoplasm, it can be associated with a fatal outcome. Treatment options have been directed at maintaining airway patency during the proliferative phase. The senior author (G.B.H.) originally described the role of the carbon dioxide laser in management of these patients in 1980. Thirty-one patients were treated for subglottic hemangioma at The Children's Hospital, Boston, between 1980 and 1990. The 10-year experience of management of subglottic hemangioma with endoscopic vaporization using the carbon dioxide laser is reviewed to assess the efficacy of this technique.

Rabies is an almost always fatal disease that physicians and patients dread due to its dismal prognosis and limited treatment options. Transmission of this disease occurs through the bite of dogs and wild animals (like jackal in our case). Other rare forms of transmission may be through inhalation in bat-infested caves and human-to-human transmission by infected corneal transplants, solid organ and tissue transplantation, and sometimes in laboratory settings. Its diagnosis is usually clinical in the absence of availability of special laboratory investigations at the point-of-care facility. Few people have described the role of imaging in diagnosis. We hereby report a patient with rabies encephalitis, having a history of jackal bite and classical MRI findings that we can use for early diagnosis in the absence of typical clinical features and specialised diagnostic testing.

Background: Poor collateral circulation and hypoperfusion may lead to recurrent stroke in intracranial atherosclerotic disease (ICAD). The role of perfusion in silent strokes and potentially insidious cognitive impairment in ICAD is unknown. We used evidence of impaired perfusion at angiography in SAMMPRIS to predict subsequent cognitive changes. Methods: Angiography at enrollment in the SAMMPRIS trial was independently evaluated, blind to clinical data and cognitive testing. Antegrade flow in the symptomatic arterial territory and corresponding collateral flow were scored. Impaired perfusion was defined by poor antegrade and poor collateral flow. Serial testing with the Montreal Cognitive Assessment (MoCA) was done in subjects without aphasia or neglect at baseline, 4 mo, 12 mo and closeout, or until subjects had a clinical stroke endpoint. Results: 207 subjects (median age 61, range 33-81 years; 37% women) had baseline MoCA scores with angiography data on territorial perfusion. Baseline MoCA scores (mean 24.2±4.1) were similar between categories of antegrade flow and collateral circulation. Impaired perfusion was noted in 33/207 (16%). Serial MoCA revealed that changes in cognition over time were different at 4 mo, 12 mo and closeout based on the presence of impaired perfusion at baseline (p<0.001). After more modest (mean MoCA change = 0.5 increase from baseline, p=0.80) early improved cognitive function at 4 mo, those with impaired perfusion had cognitive decline at 12 mo (mean MoCA change, p<0.01) unlike the continued improvement in other subjects. Cognitive changes in those with impaired perfusion were associated with a higher frequency of subsequent stroke in the territory. Conclusions: Impaired perfusion in the symptomatic arterial territory of ICAD predicts cognitive outcomes that may precede recurrent ischemia. Future studies may define the role of noninvasive perfusion imaging in ICAD to predict cognitive trajectories and recurrent stroke.

Psoriasis is a chronic inflammatory skin disease affecting nearly 10% of dermatologic patients in Malaysia. Treatment options include topical agents and phototherapy as well as nonbiologic and biologic systemic therapy. Mild psoriasis can often be managed with topical agents. However, managing moderate to severe psoriasis is more challenging and may require systemic treatment with nonbiologics or biologics. Despite the availability of several biologics, there are many unmet clinical needs, which may be addressed by secukinumab, an IL-17A inhibitor. This position statement is based on an expert panel discussion and is intended to provide dermatologists an overview of existing options as well as to provide a better understanding of secukinumab and how it can be integrated into current practice. During the discussion, panel members examined current approaches and the role of secukinumab in plaque psoriasis management. Panel members estimated that up to 30% of patients have moderate to severe psoriasis but only 1-2% receive biologics. Highlights from the discussion were that (i) the threshold for biologic use should be lower, in line with international guidelines; (ii) studies have shown that secukinumab has several advantages over other biologics which are greater efficacy, sustained efficacy over time, rapid onset of action, and early evidence of possible disease-modifying potential; and (iii) ideal candidates for secukinumab are all patients of moderate to severe psoriasis, including those with history of treatment failure, difficult-to-treat patterns of psoriasis (nail, scalp, and palmoplantar psoriasis), psoriatic arthritis, and comorbidities and those aiming for clear skin. Panel members recommend that secukinumab be considered first line option among biologic therapies.

Surgery on unruptured intracranial aneurysms (UIAs) could be a good strategy for prevention of haemorrhage, but management decisions require an accurate assessment of the risks of various treatment options, compared with the natural history of subarachnoid haemorrhage (SAH). The International Study for Unruptured Aneurysms (ISUIA) showed that the natural history is different for patients with UIAs who have not experienced SAH, than it is for patients with a history of prior SAH due to a separate aneurysm, in whom the risk is increased. The size of the UIAs is the best predictor of future rupture and the site can also be. The role of elective neuroradiological screening is the subject of discussion. In fact, the possibility of treatment should be considered on the basis of the patient's age and clinical status. Factors that favour surgery include a young patient with a long life expectancy, previously ruptured aneurysms, a familiarity, large and symptomatic aneurysms and low risk of treatment. The role of endovascular treatment is also discussed.

Background: Precision medicine in cerebrovascular disorders may be greatly advanced by the use of innovative interventional and imaging-intensive registries. Registries have remained subsidiary to randomized controlled trials, yet vast opportunities exist to leverage big data in stroke. Summary: This overview builds upon the rationale for innovative, imaging-intensive interventional registries as a pivotal step in realizing precision medicine for several cerebrovascular disorders. Such enhanced registries may serve as a model for expansion of our translational research pipeline to fully leverage the role of phase IV investigations. The scope and role of registries in precision medicine are considered, followed by a review on the history of stroke and interventional registries, data considerations, critiques or barriers to such initiatives, and the potential modernization of registry methods into efficient, searchable, imaging-intensive resources that simultaneously offer clinical, research and educational added value. Key Messages: Recent advances in technology, informatics and endovascular stroke therapies converge to provide an exceptional opportunity for registries to catapult further progress. There is now a tremendous opportunity to deploy registries in acute stroke, intracranial atherosclerotic disease and carotid disease where other clinical trials leave questions unanswered. Unlike prior registries, imaging-intensive and modernized methods may leverage current technological capabilities around the world to efficiently address key objectives and provide added clinical, research and educational value.
