Amyloid-β levels and cognitive trajectories in non-demented pTau181-positive subjects without amyloidopathy.

Brain 2022 Aug 16. Epub 2022 Aug 16.

Department of Psychiatry and Psychotherapy, Friedrich-Alexander-Universität Erlangen-Nürnberg, Erlangen, Germany.

Phosphorylated Tau181 (pTau181) in cerebrospinal fluid (CSF) and recently in plasma has been associated with Alzheimer's disease. In the absence of amyloidopathy, individuals with increased total Tau levels and/or temporal lobe atrophy experience no or only mild cognitive decline compared with biomarker-negative controls, leading to the proposal to categorize this constellation as Suspected non-Alzheimer disease pathophysiology (SNAP). We investigated whether the characteristics of SNAP also applied to individuals with increased CSF-pTau181 without amyloidopathy. Read More

Leptomeningeal Metastasis from Non-Small Cell Lung Cancer and Current Landscape of Treatments.

Clin Cancer Res 2022 Aug 16. Epub 2022 Aug 16.

St. Francis Hospital, Hartford, CT, United States.

Leptomeningeal metastasis (LM), also known as leptomeningeal carcinomatosis (LC), is a devastating complication of metastatic cancer that occurs when neoplastic cells invade the meningeal space. Diagnosis of LM remains challenging given the heterogeneous signs and symptoms at presentation and requires thorough neurological examination, cerebrospinal fluid (CSF) analysis, and magnetic resonance imaging (MRI) of the brain and spine with gadolinium. Detecting neoplastic cells in the cerebrospinal fluid is the gold standard for diagnosing leptomeningeal metastases; however, it has low sensitivity and may require multiple CSF samples. Read More

Rapid brain MRI protocols result in comparable differential diagnoses versus a full brain protocol in most canine and feline cases.

Vet Radiol Ultrasound 2022 Aug 15. Epub 2022 Aug 15.

Department of Quantitative Health Sciences, University of Massachusetts Medical School, 368 Plantation St, Worcester, Massachusetts, USA.

Evaluation of brain disease in veterinary patients uses a wide variety of MRI sequences. A shortened protocol that maintains consistency of interpretation would reduce radiologist reporting time, patient anesthetic time, and client cost. The aims of this retrospective, methods comparison, observer agreement study were to evaluate whether abbreviated MRI protocols alter differential diagnoses and recommendations compared to our institution's standard protocol; evaluate interobserver agreement on standard brain MRIs; and assess whether differential diagnoses change after postcontrast images.

Mantle cell lymphoma with aseptic meningitis mimicking hydrocephalus on brain imaging.

Nagoya J Med Sci 2022 May;84(2):470-476

Department of Community Healthcare and Geriatrics, Nagoya University Graduate School of Medicine, Nagoya, Japan.

An 83-year-old man underwent head computed tomography (CT) to investigate cognitive decline and gait disturbance and was admitted to undergo a cerebrospinal fluid (CSF) tap test for suspected idiopathic normal-pressure hydrocephalus. He had a history of chemotherapy for mantle cell lymphoma (MCL), but CT on admission showed no evidence of recurrence. After admission, his level of consciousness rapidly deteriorated and CSF examination suggested infiltration of MCL into the central nervous system (CNS). Read More

Conservative treatment for cavity spilling coronary perforations.

Cardiovasc Revasc Med 2022 Aug 8. Epub 2022 Aug 8.

Klinik für Kardiologie, Medizinische Universitätsklinik, Kantonsspital Baselland, Liestal, Switzerland. Electronic address:

Coronary perforation leading to shunting to other cardiac chambers is a rare complication of percutaneous coronary intervention (PCI), and most cases reported aggressive treatment with either a covered stent, coiling, or protamine injection. We report herein two cases, one of a fairly large cavity-spilling perforation of the left anterior descending coronary artery into the right ventricle and one spilling in the coronary vein. Both iatrogenic shunts were treated conservatively, and angiographic follow-up showed spontaneous resolution, suggesting that the outcome in this type of perforation may be favorable with conservative therapy.
