Although a greater percent of patients treated with verapamil in our electromotive drug administration protocol had a measured decrease in curvature, the results were not statistically significant. Further research is necessary to determine whether electric current may have a role in the treatment of Peyronie's disease as well as if verapamil delivered via electromotive drug administration may have a role as effective treatment. Electromotive drug administration is a treatment option in the patient whose major complaint is pain or in the patient with mild curvature who does not wish to undergo intralesional therapy or surgical correction.

IHC of Notch markers is feasible and correlates with known prognostic factors consistent with a biological role of Notch signaling in breast cancer progression.

Objective To assess the ability of 68Ga DOTA-NOC PET/computed tomography (CT) to differentiate dural metastases from meningioma. Patients and methods Patients who underwent a 68Ga DOTA-NOC PET/CT for differentiating meningiomas from dural metastases were included in the study. A visual score was assigned to the dural lesions (visual score – 1 to 3) in relation to the uptake in liver and spleen and variation in the visual score was evaluated. SUVmax of the dural lesions was also noted and difference in the values of the two pathologies were compared for statistical significance using nonparametric statistical tests. Final diagnosis was decided by histopathological confirmation whenever available. Results Imaging, histopathology or follow-up data of 42 patients was available for analysis. Meningioma was the final diagnosis in 31 (73.8%) patients, whereas dural metastases were diagnosed in 9 (21.4%) patients. In two patients, histopathology revealed inflammatory pseudotumor and hemangioblastoma. Meningiomas showed intense tracer uptake in 30/31 patients (visual score 3). All metastatic lesions showed some degree of tracer uptake though the intensity was lesser compared to meningioma (visual score 1, 2). Meningiomas showed a significantly higher median SUV max value compared to metastases (12.7 vs. 6.0, P = 0.001). Conclusion Meningiomas can be differentiated from dural metastases by virtue of their higher uptake of 68Ga-labeled DOTA peptides reflecting higher SSTR expression. An asymptomatic meningeal based lesion with a high visual score (Visual score 3) has a very high probability to be a meningioma rather than dural metastasis.
