Primary meningeal melanocytoma of the cerebellopontine angle associated with ipsilateral nevus of Ota: A case report.

Conclusion: Primary meningeal melanocytoma of the brain is a rare but benign tumor; the association between meningeal melanocytoma and nevus of Ota is also rare and possibly explained by their common embryonic origin from neural crest cells. There are six cases reported so far in literature including our case for meningeal melanocytoma associated with nevus of Ota. PMID: 30613434 [PubMed]

ConclusionPET/CT-guided molecular biopsy using Ga-68 labelled radiotracers is feasible and can be performed safely and accurately with a high-diagnostic yield. It is helpful in accurately staging the disease when tracer-avid isolated distant lesion evident on imaging and highly practical in patients with previous inconclusive sampling.

Stem cells hold a great deal of promise in treating a huge variety of human diseases. Although much hyped to the general public some years ago, it turned out to be very difficult to safely use stem cells to generate replacement tissues without inadve...

Carnio, Luiz G.S. BrancoAbstractPhysical exercise-induced inflammation may be beneficial when exercise is regular but it may be harmful when exercise is intense and performed by unaccustomed individuals/rats. Molecular hydrogen (H2) has recently emerged as a powerful anti-inflammatory, antioxidant and anti-apoptotic molecule in a number of pathological conditions, but little is known about its putative role under physi...

Abstract The combined immunotherapy of nivolumab and ipilimumab causes a variety of autoimmune-related adverse events (irAEs). The current report details a 70-year-old woman with clear cell renal cell carcinoma metastasis in the lung. Two weeks after two courses of treatment, the patient complained of headache, dizziness and nausea. Cerebrospinal fluid (CSF) analysis revealed an elevated protein level of 195 mg/dl and a significantly elevated white blood cell (WBC) count of 830/mm3 (lymphocytes, 825/mm3; neutrophils, 5/mm3). The results excluded malignancy and infection. The patient was diagnosed with aseptic meni...

Discussion The anterior cruciate ligament (ACL) “is an intra-articular but extrasynovial collagenous structure with limited healing capacity that originates in the posteromedial aspect of the lateral femoral condyle and crosses into anteromedially to insert anterior into the intercondylar eminence of tibial articular surface.” It plays an important part as a mechanoreceptor particularly as a proprioceptor. Its main role is to prevent excessive anterior tibial translation, limits varus/valgus stress when the knee is in full extension and some rotary movements of the knee. There are ~120,000 surgeries per year m...

In Reply We agree with Popkirov that left atrial volume is a better marker of incident atrial fibrillation than atrial diameter; however, we did not have these data available at all of the sites participating in the New Approach Rivaroxaban Inhibition of Factor Xa in a Global Trial Versus ASA to Prevent Embolism in Embolic Stroke of Undetermined Source (NAVIGATE-ESUS) trial. Recently completed and ongoing studies will help determine if our observation has a clinical role and may provide additional data on left atrial size and function. Once all of these data are available, guidelines committees will likely make recommendat...

To the Editor In a secondary analysis of the New Approach Rivaroxaban Inhibition of Factor Xa in a Global Trial Versus ASA to Prevent Embolism in Embolic Stroke of Undetermined Source trial, Healey and colleagues determined that for patients with embolic stroke of undetermined source and left atrial enlargement rivaroxaban treatment was associated with a 74% reduction in recurrent stroke. The authors suggest that left atrial enlargement could become a new determinant in secondary stroke prevention.

ConclusionRight-hemispheric symptoms appear to be less clinically conspicuous resulting in a delayed diagnosis of GBM, which might be improved by raising awareness for the corresponding neuropsychological deficits. Whether our findings have prognostic implications needs to be evaluated in future studies.

AbstractPurposeFor meningiomas, the 2016 revision of the WHO classification introduced brain invasion per se as a sufficient condition to classify as grade II. We analyzed whether meningiomas previously graded as WHO grade I differ in prognosis depending on the presence of microscopic brain invasion.MethodsA consecutive series of patients with intracranial meningioma WHO grade I ( ± brain invasion) at two neurosurgical departments was analyzed retrospectively. Cox regression models on progression-free survival (PFS) and Kaplan–Meier survival estimates were performed.Results875 adult patients were included. His...

The objectives of this systematic review were to investigate the role of HRM in the assessment of SSc-associated upper GI involvement and to evaluate the correlation between HRM abnormalities and clinical characteristics and the effects of therapeutic interventions on HRM findings. Fifteen articles were included. Most (11/15) studies were of very good or good quality. Most studies assessed correlations between esophageal symptoms and esophageal dysmotility. Two studies assessed the effectiveness of buspirone and reported HRM findings. Studies assessing upper GI symptoms using validated questionnaires, such as the Universit...
