[Alopecia-keep a cool head].

Pathologe 2020 Jun 4. Epub 2020 Jun 4.

Univ. Klinik für Dermatologie und Venerologie, Medzinische Universität Graz, Auenbruggerplatz 9, 8036, Graz, Österreich.

Pathologists often feel discomfort when confronted with scalp biopsies, especially in the case of horizontal sectioning, which is particularly useful in the event of nonscarring alopecia. Apart from a profound knowledge of follicular anatomy, one should be capable of correlating the histologic information with the clinical features of various inflammatory scalp disorders. This review addresses the basic principles of the interpretation of scalp biopsies and discusses the most common forms of scarring and nonscarring alopecia. Read More

Malignant Fibrous Histiocytoma of the Scalp with Skull Invasion: A Rare and Aggressive Presentation.

Cureus 2020 Apr 23;12(4):e7801. Epub 2020 Apr 23.

Plastic, Reconstructive and Hand Surgery, Northwell Health/Donald and Barbara Zucker School of Medicine, Staten Island University Hospital, Staten Island, USA.

Malignant fibrous histiocytoma (MFH) is an undifferentiated high-grade pleomorphic sarcoma and is considered the most common primary soft tissue sarcoma in adults. MFH is known to arise in the trunk, extremities and retroperitoneum although it can arise anywhere in the body.MFH of the skin is uncommon and even less frequent is the involvement of the scalp, especially with skull invasion.

Associations between objective measures of physical activity, sleep and stress levels among preschool children.

BMC Pediatr 2020 May 27;20(1):258. Epub 2020 May 27.

Research Unit for Dietary Studies, The Parker Institute, Bispebjerg and Frederiksberg Hospital, The Capital Region, Frederiksberg, Denmark.

Background: Cortisol is often used as a biological marker for stress. When measured in urine or serum, representing a short-term measurement of the hormone, it has been associated with unfavorable sleep characteristics and both low and high physical activity levels. However, cortisol in hair represents a long-term stress measure and has been suggested as a promising new marker for chronic stress. Read More

Computational modeling of the auditory brainstem response to continuous speech.

J Neural Eng 2020 May 27. Epub 2020 May 27.

Bioengineering, Imperial College London, London, UNITED KINGDOM OF GREAT BRITAIN AND NORTHERN IRELAND.

Objective: The auditory brainstem response can be recorded non-invasively from scalp electrodes and serves as an important clinical measure of hearing function. We have recently shown how the brainstem response at the fundamental frequency of continuous, non-repetitive speech can be measured, and have used this measure to demonstrate that the response is modulated by selective attention. However, different parts of the speech signal as well as several parts of the brainstem contribute to this response. Read More

Recalcitrant lichen planopilaris and frontal fibrosing alopecia responding to tildrakizumab.

Dermatol Ther 2020 May 26:e13694. Epub 2020 May 26.

Sinclair Dermatology, 2 Wellington Parade, East Melbourne, VIC, Australia.

Lichen planopilaris (LPP) and frontal fibrosing alopecia (FFA) are lymphocytic, cicatricial alopecias. Clinically, LPP presents with multifocal patchy alopecia, while FFA, considered a variant of LPP, results in hairline recession. Frontal recession in FFA may progress as far as the mid-scalp and infrequently beyond. Read More

Real-time Inference and Detection of Disruptive EEG Networks for Epileptic Seizures.

Sci Rep 2020 May 26;10(1):8653. Epub 2020 May 26.

Department of Electrical and Systems Engineering, Washington University in St. Louis, St. Louis, MO, 63130, USA.

Recent studies in brain science and neurological medicine paid a particular attention to develop machine learning-based techniques for the detection and prediction of epileptic seizures with electroencephalogram (EEG). As a noninvasive monitoring method to record brain electrical activities, EEG has been widely used for capturing the underlying dynamics of disruptive neuronal responses across the brain in real-time to provide clinical guidance in support of epileptic seizure treatments in practice. In this study, we introduce a novel dynamic learning method that first infers a time-varying network constituted by multivariate EEG signals, which represents the overall dynamics of the brain network, and subsequently quantifies its topological property using graph theory.
