Lipedematous scalp (LS) and Lipedematous Alopecia (LA) are uncommon disorders of unknown etiology, pathogenesis and treatment. They are characterized by thickening of the subcutaneous layer of the scalp and a boggy scalp on palpation. Also, hair loss or shortening of hair is seen in LA. In this report, we describe LS in a 42-year-old woman presented with a diffuse thickened and spongy scalp. To...

Electric currents produced by the neural activity in the brain create electric potentials on the scalp and magnetic field distribution outside the scalp. Measuring electric and magnetic fields provides a means to understand the spatio-temporal distribution of the neural activity. The representations of the intracellular electric current of active cell populations based on bimodal data are calle...

Background/Aims: Dry, itchy and inflamed scalp conditions are common and often associated with diseases such as atopic dermatitis or psoriasis. To improve these symptoms, we investigated the efficacy of a new tonic containing the active ingredients urea, lactate, polidocanol, and Glycyrrhiza inflata root extract, containing licochalcone A. Study Design/Methods: 30 subjects with dry and itchy sc...

BACKGROUND Lichen planopilaris (LPP) is an inflammatory disease characterized by a lymphomononuclear infiltrate surrounding the isthmus and infundibulum of the hair follicle of the scalp, that evolves into atrophic/scarring alopecia. In the active phase of the disease hairs are easily plucked with anagen-like hair-roots. In this study we focused on the expression of integrins and basement membr...

OBJECTIVE Electromyogram (EMG) contamination is often a problem in electroencephalogram (EEG) recording, particularly, for those applications such as EEG-based brain-computer interfaces that rely on automated measurements of EEG features. As an essential prelude to developing methods for recognizing and eliminating EMG contamination of EEG, this study defines the spectral and topographical char...

We report a Principal Component Analysis (PCA) and the scalp distribution of the normalized peak amplitude values for speech-related auditory Event-related Potentials (ERP) P150-250 and N250-550 in 7-, 11-, and 20-month-old American infants learning English and in 10-13-month-old Mexican infants learning Spanish. After assessing the infant auditory ERP P-N complex using PCA, we evaluated the to...

background and objective: neurofibromas occur as solitary and multiple forms. the solitary ones are extraneural and more common, histologically exhibiting spindle cells with wavy nuclei, scattered among collagen fibers. multiple neurofibromas are seen in neurofibromatosis (types i and ii), including intraneural (plexiform, cutaneous deep circumscribed) and extraneural (cutaneous, deep diffuse) ...

aplasia cutis conginita (acc) is a condition characterized by congenital absence of skin, usually on the scalp. acc can occur as an isolated condition or in the presence of other congenital anomalies. here we describe a case of a 16 days old baby girl with an isolated acc of the scalp. her elder two siblings have been diagnosed with acc with concomitant cardiac or limb anomalies. the patient wa...

BACKGROUND Lichen planopilaris is a frequent presentation of primary cicatricial alopecia. Scalp distribution characterizes the main clinical presentations: classic lichen planopilaris, frontal fibrosing alopecia and Graham-Little Piccardi-Lassueur Syndrome (GLPLS). OBJECTIVE Description of the clinical, dermoscopic and histopathological findings of Lichen planopilaris in public and private p...

PURPOSE The aim of this paper is to report the treatment of angiosarcoma of the scalp. High-dose-rate (HDR) brachytherapy with an individual mold applicator is presented. CASE DESCRIPTION A case of a 75-year-old male will be presented with multicentric lesions over the scalp in the temple and crown region. Biopsy diagnosis was angiosarcoma of the scalp, nonoperable. The patient was qualified ...
