Skin Colonization by Malassezia Species in
Neonates: A Prospective Study and Relationship With Neonatal Cephalic Pustulosis
Malassezia species have been implicated as
the pathogens in several superficial dermatologic conditions, including tinea
versicolor and seborrheic dermatitis. Occasionally, Malassezia has also been implicated in more invasive disease, particularly in
neonates. Bernier et al demonstrate the rapid progressive colonization of
neonates by Malassezia species and note the association
with cephalic pustulosis (neonatal acne).

Herbal Therapy in Dermatology
Herbal therapy is becoming increasingly commonly used by patients and
dermatologists alike. Bedi and Shenefelt offer an excellent overview of the
efficacy, safety profile, and drug interactions of many of the plant-derived
therapies that our patients are using on a regular basis.

Comparative In Vitro Pediculicidal Efficacy of Treatments in a Resistant
Head Lice Population in the United States
Head lice infestation is an increasing problem among school-aged children
in the United States and around the world. Treatment failure is also being
observed with increasing frequency. Meinking et al compare the efficacy of
several commercially available pediculicides, revealing that many have become
less effective over time, with the exception of 0.5% malathion.

Follicular Mucinosis: A Critical Reappraisal of Clinicopathologic Features
and Association With Mycosis Fungoides and Sézary Syndrome
Follicular mucinosis may occur in many diverse settings, notably in
mycosis fungoides or Sézary syndrome. A number of histologic criteria
have been proposed to differentiate benign idiopathic follicular mucinosis
from the mycosis fungoides–associated cases. Cerroni et al find these
criteria ineffective in this retrospective survey and suggest that idiopathic
follicular mucinosis may actually represent a localized form of cutaneous
T-cell lymphoma.

Familial Confluent and Reticulated Papillomatosis
The pathophysiology of confluent and reticulated papillomatosis remains
unknown. Although cases of familial confluent and reticulated papillomatosis
have been reported, they have shed little light on the cause of this disorder.  nalöz
et al are the first to examine the ultrastructural and immunohistochemical
studies in such familial cases. They suggest that abnormal keratinocyte differentiation
may play an etiologic role in these cases.
