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) ...

The scalp potentials originate in neuronal activity in the brain cortex, and neuronal abnormality causes scalp potential abnormality. As a measure of scalp potential abnormality, the normalized power variance, NPV, of EEG signals is introduced, where its mean m and standard deviation are defined for each of 21 EEG channel over a group of normal controls. When an NPV value of a subject to be tes...

A 6-year-old patient with cerebral palsy was treated with Chinese scalp acupuncture. The Speech I, Speech II, Motor, Foot motor and sensory, and Balance areas were stimulated once a week, then every other week for 15 sessions. His dysarthria, ataxia, and weakness of legs, arms, and hands showed significant improvement from each scalp acupuncture treatment, and after 15 sessions, the patient had...

Eccrine porocarcinoma is a rare malignant adnexal tumor of ductal portion of eccrine sweat gland. It occurs commonly in the lower extremities and rarely in scalp, face, ear, trunk and upper extremities. This survey presents a classic case of eccrine porocarcinoma of scalp in a 58 yr old male patient, presenting as cauliflower like growth over parietal aspect of scalp.

Complex multiple arteriovenous fistula (AVF) of the scalp is an extremely rare disease and the traditional treatment is either endovascular embolization or surgical resection with preoperative endovascular embolization. Here, a 34-year-old male with pulsating mass and multiple tortuous vessels in front of the left tragus and scalp who was diagnosed as complex multiple arteriovenous fistula of t...

Scalp lacerations are frequently seen in both living trauma victims and at post-mortem examination. In clinical circles, it is well known that even "trivial" lacerations of blood-rich areas such as the scalp may bleed profusely and persistently.It is less well known, however, that hemorrhage even from simple scalp lacerations may be fatal. We present seven cases in which hemorrhage from simple ...

BACKGROUND A sensitive scalp is a frequent problem in daily clinical practice and often represents a major challenge for dermatologists. OBJECTIVE The objective was to evaluate the efficacy of a Northamerican Virginian Witch Hazel (Hamamelis virginiana)-based shampoo and tonic (Erol(®) Energy) for treatment of the sensitive scalp. METHODS Retrospective observational study of male and female...

OBJECTIVE After observing 2 cases of acute telogen effluvium induced by allergic contact dermatitis to hair dyes, we decided to evaluate the effects of acute contact dermatitis of the scalp on the hair cycle. DESIGN Single-center, 6-month study of consecutive patients affected by acute scalp dermatitis. SETTING Department of Dermatology, University of Bologna, Bologna, Italy. PATIENTS Dia...

Total scalp avulsion is a rare but serious injury often resulting in defects of the hair-bearing skin, and it may even be life-threatening. Microsurgical hair-bearing scalp replantation is the first choice for the treatment of scalp avulsion. In this article, we describe the microsurgical replantation of two cases with total scalp avulsion. The avulsed scalp involved the hairy scalp, forehead, ...

Scalp soft tissue expansion is one of the key medical techniques to generate new skin tissue for correcting various abnormalities and defects of skin in plastic surgery. Therefore, it is very important to work out the appropriate approach to evaluate the increase of expanded scalp area and to predict the shape, size, number, and placement of the expander. A novel method using finite element mod...
