BACKGROUND Seborrheic dermatitis (SD) is a common inflammatory skin condition. The etiology is unclear, although overgrowth of Malassezia on the skin has been suggested to cause SD. This study investigated whether colonization with Staphylococcus plays a role in facial SD, which was not well addressed previously. METHODS The study was conducted from September 1, 2011 to February 20, 2012 in t...

The human scalp harbors a vast community of microbial mutualists, the composition of which is difficult to elucidate as many of the microorganisms are not culturable using current culture techniques. Dandruff, a common scalp disorder, is known as a causative factor of a mild seborrheic dermatitis as well as pityriasis versicolor, seborrheic dermatitis, and atopic dermatitis. Lipophilic yeast Ma...

BACKGROUND Seasonal variation has been demonstrated in many diseases, including certain skin diseases. OBJECTIVE To determine whether there is seasonal variation in dermatologic office visits in the USA. METHODS Data on dermatologic office visits were obtained from representative visits to outpatient physicians in the USA from the National Ambulatory Medical Care Survey from 1990 to 1998. O...

BACKGROUND Both the skin and the neurologic system are derived from the ectoderm during embryogenesis, and thus patients with neurologic disorders may have accompanying dermatologic diseases. For example, seborrheic dermatitis is more frequently observed in patients with Parkinsonism and other neurologic disorders. To date, however, there has been limited review on dermatologic diseases in neur...

BACKGROUND Malassezia species (spp.) are cutaneous opportunistic pathogens and associated with various dermatological diseases including seborrheic dermatitis, dandruff and atopic dermatitis. Almost all Malassezia spp. are obligatorily lipid-dependent, which might be caused by lack of the myristic acid synthesis. Recent genome analysis of M. restricta and M. globosa suggested that the absence o...

Sir, Down’s syndrome (trisomy 21) is a multisystem disorder with a birth incidence of approximately 1 in 700 live births, making it the most common autosomal chromosomal disorder causing mental retardation. Down’s Syndrome is also associated with an increased incidence of cutaneous disorders.[1-4] In particular, there seems to be an increased incidence of xerosis, atopic dermatitis, seborrheic ...
