Frontal-occipital network alterations while viewing 2D & 3D movies: a source-level EEG and graph theory approach.

Biomed Tech (Berl) 2022 May 16. Epub 2022 May 16.

School of Life Sciences, College of International Education, Institute of Biomedical Engineering, Shanghai University, Shanghai, China.

Many researchers have measured the differences in electroencephalography (EEG) while viewing 2D and 3D movies to uncover the neuromechanism underlying distinct viewing experiences. Using whole-brain network analyses of scalp EEG, our previous study reported that beta and gamma bands presented higher global efficiencies while viewing 3D movies. However, scalp EEG is influenced by volume conduction, not allowing inference from a neuroanatomy perspective; thus, source reconstruction techniques are recommended. Read More

A Rare Presentation of Dermatofibrosarcoma Protuberans of the Scalp Treated with "Slow-Mohs" Micrographic Surgery.

J Drugs Dermatol 2022 May;21(5):534-535

Dermatofibrosarcoma protuberans (DFSP) is a rare, fibrohistiocytic tumor with intermediate malignancy.1 While these tumors are slow-growing and only metastasize in 6% of cases,2 they are often locally destructive, with relatively high local recurrence rates after initial excision. Overall annual incidence rates in the US are 0. Read More

Current trends in craniofacial reconstruction.

Surgeon 2022 May 4. Epub 2022 May 4.

Department of Plastic & Reconstructive Surgery, Beaumont Hospital, Dublin, Ireland.

Reconstruction of the head and neck continues to pose a variety of difficult functional and aesthetic challenges to the plastic surgeon. While the surgical treatment for midfacial and skull base tumours continues to advance, the three-dimensional reconstruction predicaments continue to increase in complexity. Reconstructive strategies of the head and neck require the restoration of intricate skeletal architecture and large volumes of both internal and external soft tissue envelopes that can withstand adjuvant therapies.

A case of pleomorphic dermal sarcoma with perineural invasion treated with Mohs micrographic surgery and adjuvant radiation therapy.

Dermatol Online J 2022 Jan 15;28(1). Epub 2022 Jan 15.

Rutgers Robert Wood Johnson Medical School, Piscataway, New Jersey, USA Dermatology Service, VA New York Harbor Healthcare System, Brooklyn, New York, USA.

Pleomorphic dermal sarcoma (PDS) was recognized in the 2013 World Health Organization Classification of Tumors of Soft Tissue and Bone as a clinical entity with adverse histopathologic features compared to the more superficial and less aggressive atypical fibroxanthoma (AFX). Although the gold standard treatment of AFX is Mohs micrographic surgery (MMS), the optimal treatment for PDS has yet to be determined. We report the case of a 71-year-old man with a PDS with perineural invasion on the scalp, with no recurrence one-year post-treatment with MMS and adjuvant radiation therapy. Read More

Accelerated Cranioplasty with Perforator-preserved Split Flap Sandwiched Plate for Treatment of Infected Cranial Defects.

Plast Reconstr Surg Glob Open 2022 Apr 8;10(4):e4234. Epub 2022 Apr 8.

Department of Plastic and Reconstructive Surgery, Mie University, Tsu, Japan.

Large cranial vault defects are challenging to manage due to the need to balance infection control, skin coverage, and restoration of the protective mechanical rigidity of the skull while also ensuring good head and neck aesthetic results. Conventional-staged treatment requires a long time period that includes debridement and scalp skin defect coverage with flaps as a first step, followed by definitive plate reconstruction 3-9 months later after infection control and flap atrophy resolution. We report a case of successful early cranioplasty in a factory worker who developed a large full-thickness cranial skull defect following artificial dura infection. Read More

Ultra-rapid and automatic interplay between L1 and L2 semantics in late bilinguals: EEG evidence.

Cortex 2022 Jun 24;151:147-161. Epub 2022 Mar 24.

Centre for Cognition and Decision Making, Institute for Cognitive Neuroscience, HSE University, Moscow, Russian Federation; Center of Functionally Integrative Neuroscience, Aarhus University, Aarhus, Denmark.

Converging behavioral and neuroimaging evidence suggests parallel activation of native (L1) and second (L2) language codes in bilinguals, with the modulation of the N400 as the most likely neural correlate of such L1-L2 interplay at lexico-semantic level. However, this relatively late effect may reflect secondary controlled processes, in contrast to earlier modulations found in monolinguals (<200 msec) indicative of fast and automatic lexico-semantic L1 access, which has so far not been documented for bilingualism. To address this, we investigated early neurophysiological crosslinguistic activation during bilingual word access. Read More

Covering of large scalp defects prior to postoperative irradiation.

J Dtsch Dermatol Ges 2022 05 11;20(5):611-616. Epub 2022 Apr 11.

Klinik und Poliklinik für Dermatologie, Venerologie und Allergologie, Universitätsklinik Leipzig AöR, Leipzig.

Background And Objective: After R0 resection of extensive cutaneous squamous cell carcinoma of the scalp with indication for postoperative radiotherapy, closure techniques should be chosen that allow rapid initiation of radiotherapy. The aim of this retrospective analysis is to evaluate defect coverage by transverse transposition flap and split skin grafting of the donor site in such a scenario with regard to oncologic safety (recurrence rate) and permanence of wound closure.

Patients And Methods: Eleven patients were identified who had histologic cutaneous squamous cell carcinoma treated by microscopically controlled excision and defect coverage using a transverse transposition flap and split skin grafting of the donor site and who received postoperative radiotherapy.

Ten-year experience with laparoscopic pedicled omental flap for cerebral revascularization in patients with Moyamoya disease.

J Pediatr Surg 2022 Jan 31. Epub 2022 Jan 31.

Division of Pediatric Surgery, Department of Surgery, Stanford University School of Medicine, 730 Welch Rd, Stanford, Palo Alto, CA 94304, United States. Electronic address:

Background: The omental flap has numerous extraperitoneal applications in reconstruction and revascularization given its favorable immunologic and angiogenic properties. In patients with Moyamoya disease, cerebral revascularization using a pedicled omental flap has proven to be a viable option following direct revascularization procedures. Historically, harvesting omentum involved laparotomy with the associated risk of complications; herein we describe outcomes from a 10-year experience of laparoscopic harvesting of pedicled omental flap for cerebral revascularization in Moyamoya patients.

Diffuse optical reconstructions of functional near infrared spectroscopy data using maximum entropy on the mean.

Sci Rep 2022 02 10;12(1):2316. Epub 2022 Feb 10.

Department of Physics and PERFORM Centre, Concordia University, Montreal, Canada.

Functional near-infrared spectroscopy (fNIRS) measures the hemoglobin concentration changes associated with neuronal activity. Diffuse optical tomography (DOT) consists of reconstructing the optical density changes measured from scalp channels to the oxy-/deoxy-hemoglobin concentration changes within the cortical regions. In the present study, we adapted a nonlinear source localization method developed and validated in the context of Electro- and Magneto-Encephalography (EEG/MEG): the Maximum Entropy on the Mean (MEM), to solve the inverse problem of DOT reconstruction.

Institute of Mathematics, Physics and Mechanics, Ljubljana, Slovenia.

Optically pumped magnetometers (OPMs) have recently become so sensitive that they are suitable for use in magnetoencephalography (MEG). These sensors solve operational problems of the current standard MEG, where superconducting quantum interference device (SQUID) gradiometers and magnetometers are being used. The main advantage of OPMs is that they do not require cryogenics for cooling. Read More
