BACKGROUND AND OBJECTIVE Tissue expansion is a time-tested and frequently used procedure for utilizing local tissue to replace large defects. We aimed to assess the success & complications of tissue expansion in correction of post burn scalp alopecia. METHODS In this study, 30 patients of scalp burn alopecia of 5 to 35 years age group were treated with tissue expansion of the scalp at Bahawal...

BACKGROUND Central centrifugal cicatricial alopecia (CCCA) is the most common cause of scarring alopecia among women of African descent which affects the central scalp and spreads centrifugally but spares the lateral and posterior scalp. OBJECTIVES The objective of this study is to report on a new clinical variety of CCCA presenting with patchy alopecia involving the lateral and posterior sca...

INTRODUCTION Defects of the scalp arise from several aetiologies including trauma, burn, injury, infection, radiation and surgical excision of tumours. Multiple options for reconstruction of scalp defects exist that included primary closure, skin grafts, local flaps, regional and distal free flaps. PATIENTS AND METHODS This was a prospective case-series study, which was carried out in the Dep...

Scalp psoriasis shows a variable clinical spectrum and in many cases poses a great therapeutic challenge. However, it remains unknown whether the immune response of scalp psoriasis differs from understood pathomechanisms of psoriasis in other skin areas. We sought to determine the cellular and molecular phenotype of scalp psoriasis by performing a comparative analysis of scalp and skin using le...

In order to quantitatively investigate the importance of transfollicular pathway for drug delivery, drug penetration through human scalp skin was investigated using liquid formulations containing lipophilic and hydrophilic drugs in vitro. The penetration pathway for drugs through the scalp skin was examined using fluorescent probes. Additionally, the drug penetration through the scalp skin was ...

Measurements of human brain function in children are of increasing interest in cognitive neuroscience. Many techniques for brain mapping used in children, including functional near-infrared spectroscopy (fNIRS), electroencephalography (EEG), magnetoencephalography (MEG) and transcranial magnetic stimulation (TMS), use probes placed on or near the scalp. The distance between the scalp and the br...

Functional near-infrared imaging (fNIRI) is a non-invasive, low-cost and highly portable technique for assessing brain activity and functions. Both clinical and experimental evidence suggest that fNIRI is able to assess brain activity at associated regions during pain processing, indicating a strong possibility of using fNIRI-derived brain activity pattern as a biomarker for pain. However, it r...

INTRODUCTION Scalp and calvarial defects may result from trauma, thermal or electrical burns, resection of benign or malignant tumors, infections or radionecrosis. Reconstruction of large scalp defects is a demanding procedure. The reconstructive "ladder" are applicable to scalp and calvarial defects reconstruction. CASE OUTLINE A 68-year-old female was admitted to our clinic due to the nine-...

Dandruff is an unpleasant scalp disorder common to human populations. In this study, we systematically investigated the intra- and inter-associations among dandruff, physiological conditions such as sebum of the scalp, host demographics such as gender, age and the region of the scalp, and the microorganisms on the scalp. We found that the physiological conditions were highly relevant to the hos...
