“…The findings in PWS suggest that endogenous techniques may alter the relative contributions of both feedforward and feedback control, though further investigation is necessary. It also is interesting to consider how other endogenous fluency enhancing motor manipulations, such as whispering (Bloodstein, 1950 ) and accent modification (Bloodstein, 1950 ) might alter sensorimotor control in both PWS and neurotypical populations.…”

Objective: To determine whether changes in sensorimotor control resulting from speaking conditions that induce fluency in people who stutter (PWS) can be measured using electroencephalographic (EEG) mu rhythms in neurotypical speakers.Methods: Non-stuttering (NS) adults spoke in one control condition (solo speaking) and four experimental conditions (choral speech, delayed auditory feedback (DAF), prolonged speech and pseudostuttering). Independent component analysis (ICA) was used to identify sensorimotor μ components from EEG recordings. Time-frequency analyses measured μ-alpha (8–13 Hz) and μ-beta (15–25 Hz) event-related synchronization (ERS) and desynchronization (ERD) during each speech condition.Results: 19/24 participants contributed μ components. Relative to the control condition, the choral and DAF conditions elicited increases in μ-alpha ERD in the right hemisphere. In the pseudostuttering condition, increases in μ-beta ERD were observed in the left hemisphere. No differences were present between the prolonged speech and control conditions.Conclusions: Differences observed in the experimental conditions are thought to reflect sensorimotor control changes. Increases in right hemisphere μ-alpha ERD likely reflect increased reliance on auditory information, including auditory feedback, during the choral and DAF conditions. In the left hemisphere, increases in μ-beta ERD during pseudostuttering may have resulted from the different movement characteristics of this task compared with the solo speaking task. Relationships to findings in stuttering are discussed.Significance: Changes in sensorimotor control related feedforward and feedback control in fluency-enhancing speech manipulations can be measured using time-frequency decompositions of EEG μ rhythms in neurotypical speakers. This quiet, non-invasive, and temporally sensitive technique may be applied to learn more about normal sensorimotor control and fluency enhancement in PWS.

Background: Endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) is the diagnostic tool of choice for pancreatic solid mass lesions. Pancreatic lymphomas represent an infrequent and challenging cytologic diagnosis. Our aim was to determine the diagnostic value of cellblock (CB) in the diagnosis of pancreatic lymphomas. Methods: We retrieved pancreatic EUS-FNAs performed over 10-years from our institution’s database. We correlated the cytologic and CB diagnosis with the histologic diagnosis as a gold standard. Results: We found 5 cases (2 women and 3 men; age range, 37–66 years [average age, 52 years]) of pancreatic lymphomas with histologic follow-up biopsies. They included 1 case of T-cell lymphoma (TCL), 1 case of plasma cell neoplasm (multiple myeloma [MM]), 1 case of diffuse large B-cell lymphoma (DLBCL), 1 case of classic Hodgkin lymphoma (HL), and 1 case of high-grade B-cell lymphoma (HGBCL). Cytologically, the cases of HL and DLBCL were suspected, the cases of TCL and MM were confused with undifferentiated carcinoma and neuroendocrine carcinoma, and the case of HGBCL was inconclusive. CB samples were of value in highlighting the morphologic details of lymphomas and allowed confirmation, proper classification, and grading of the lymphomas using immunohistochemistry that matched tissue biopsies. Conclusions: EUS-FNA smears with CBs are helpful diagnostic tools, differentiating lymphomas from other malignancies and from nonneoplastic lymphocyte-rich lesions. CBs allow proper classification and grading of cases of pancreatic lymphomas.

Osteoclast-like giant cell tumor of the pancreas is very rare. We report a 78-year-old male who was previously treated for large mantle cell lymphoma, was found to have an increased uptake in a peri-pancreatic node from his restaging PET scan. Endoscopic ultrasound-directed fine-needle aspiration of the mass and lymph node revealed an undifferentiated carcinoma with osteoclast-like giant cells. Osteoclast-like giant cell tumors of the pancreas are frequently found to be unresectable at diagnosis due to their large size (>5 cm). In our patient, due to its small size (<3 cm) sub-total pancreatectomy was performed. Three years from the surgery, the patient is doing well without recurrence. This case report intends to increase provider awareness that in the setting of new pancreatic lesions in a patient with previous history of lymphoma, a high index of suspicion for a primary pancreatic lesion should be included in the differential diagnosis.
