Abstract
BACKGROUND Topical vitamin D is approved by the US Food and Drug Administration for the treatment of psoriasis but is also used off-label in the treatment of a variety of cutaneous diseases despite a lack of evidence-based guidelines. OBJECTIVE The objective of this study was to provide evidence-based clinical guidelines for the off-label use of topical vitamin D in the treatment of dermatologic disease. METHODS A systematic literature review was conducted via the MEDLINE, Embase, and CENTRAL databases for off-label uses of topical vitamin D analogues in the treatment of dermatologic disease other than psoriasis. The data were synthesized, and evidence-based recommendations were rendered according to the highest level of evidence available. RESULTS A total of 165 articles met the inclusion criteria. A moderate to strong recommendation was given for the use of topical vitamin D in combination with corticosteroids and phototherapy in vitiligo and as monotherapy for various ichthyoses, morphea, pityriasis alba, prurigo nodularis, and polymorphous light eruption. There is evidence showing that topical vitamin D is ineffective in the treatment of actinic keratosis, seborrheic keratosis, lichen planus, seborrheic dermatitis, alopecia areata, chemotherapy-induced alopecia, and hypertrophic scars. CONCLUSION Topical vitamin D analogues have an important role in the off-label treatment of dermatologic disease, but higher quality studies are still required.

Distribution of Malassezia species on the skin of patients with atopic dermatitis, psoriasis, and healthy volunteers assessed by conventional and molecular identification methods. BMC DERMATOLOGY 2014; 14:3. [PMID: 24602368 PMCID: PMC3975586 DOI: 10.1186/1471-5945-14-3] [Citation(s) in RCA: 63] [Impact Index Per Article: 6.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 09/04/2013] [Accepted: 03/01/2014] [Indexed: 01/14/2023]
Abstract
Background The Malassezia yeasts which belong to the physiological microflora of human skin have also been implicated in several dermatological disorders, including pityriasis versicolor (PV), atopic dermatitis (AD), and psoriasis (PS). The Malassezia genus has repeatedly been revised and it now accommodates 14 species, all but one being lipid-dependent species. The traditional, phenotype-based identification schemes of Malassezia species are fraught with interpretative ambiguities and inconsistencies, and are thus increasingly being supplemented or replaced by DNA typing methods. The aim of this study was to explore the species composition of Malassezia microflora on the skin of healthy volunteers and patients with AD and PS. Methods Species characterization was performed by conventional, culture-based methods and subsequently molecular techniques: PCR-RFLP and sequencing of the internal transcribed spacer (ITS) 1/2 regions and the D1/D2 domains of the 26S rRNA gene. The Chi-square test and Fisher’s exact test were used for statistical analysis. Results Malassezia sympodialis was the predominant species, having been cultured from 29 (82.9%) skin samples collected from 17 out of 18 subjects under the study. Whereas AD patients yielded exclusively M. sympodialis isolates, M. furfur isolates were observed only in PS patients. The isolation of M. sympodialis was statistically more frequent among AD patients and healthy volunteers than among PS patients (P < 0.03). Whether this mirrors any predilection of particular Malassezia species for certain clinical conditions needs to be further evaluated. The overall concordance between phenotypic and molecular methods was quite high (65%), with the discordant results being rather due to the presence of multiple species in a single culture (co-colonization) than true misidentification. All Malassezia isolates were susceptible to cyclopiroxolamine and azole drugs, with M. furfur isolates being somewhat more drug tolerant than other Malassezia species. Conclusions This study provides an important insight into the species composition of Malassezia microbiota in human skin. The predominance of M. sympodialis in both normal and pathologic skin, contrasts with other European countries, reporting M. globosa and M. restricta as the most frequently isolated Malassezia species.

Abstract
Background A Pyrosequencing assay has been used in identification of fungal species such as Candida or Aspergillus and diagnosis of pathogenic bacteria such as Helicobacter pylori but there has been no report on successful isolation and identification of Malassezia yeasts using the pyrosequencing method. Objective Examine the applicability and plausibility of the pyrosequencing method in identification of the Malassezia species. Methods At internal transcribed spacer (ITS) sites 1 and 2, three primers were developed using Pyrosequencing Assay Design Software (Biotage AB). Pyrosequencing was performed on 11 standard strains and 83 genomic DNA samples obtained from 66 healthy controls aged from 1 to 80. Results The eleven Malassezia standard species and 83 genomic DNA samples were successfully identified using the pyrosequencing assay. Conclusion The pyrosequencing method is a new tool for analysis of Malassezia yeasts, and its precision and rapidity suggests its clinical applicability.

Abstract
We herein report a sporadic case of Darier's disease localized to the bilateral side of the neck in a 39-year-old Japanese woman. Several clinical variants of Darier's disease have so far been recognized including unilateral Darier's disease, localized Darier's disease, segmental Darier's disease and acral Darier's disease. Few cases of Darier's disease, restricted to sun-exposed areas such as the bilateral side of the neck, have been described in the published work. It remains controversial, however, whether ultraviolet exposure can induce the onset of Darier's disease. Our patient's skin lesions, which were resistant to previous treatment with corticosteroid, improved substantially with high-concentration tacalcitol lotion and sunscreen. This is the first report on the efficacy of topical tacalcitol lotion associated with sunscreen for the treatment of localized Darier's disease.

Abstract
BACKGROUND This case-control study concerns a molecular biological method based on the data gathered from a group of Korean subjects to examine the distribution of Malassezia yeasts in seborrheic dermatitis (SD) patients. Cultures for Malassezia yeasts were taken from the foreheads, cheeks and chests of 60 patients with SD and in 60 healthy controls of equivalent age. OBJECTIVE The purpose of this study is to identify the relationship between certain species of Malassezia and SD. This was done by analyzing the differences in the distribution of Malassezia species in terms of age and body parts of the host with healthy controls. METHODS 26S rDNA PCR-RFLP, a fast and accurate molecular biological method, was used to overcome the limits of morphological and biochemical methods. RESULTS The positive Malassezia culture rate was 51.7% in patients with SD, which was lower than that of healthy adults (63.9%). M. restricta was dominant in patients with SD (19.5%). Likewise, M. restricta was identified as a common species (20.5%) in healthy controls. In the ages 31~40, M. restricta was found to be the most common species (31.6%) among SD patients. CONCLUSION According to the results of the study, the most frequently isolated species was M. restricta (19.5%) in patients with SD. There was no statistically significant difference in the distribution of Malassezia species between the SD patients and healthy control groups.

Abstract
BACKGROUND Malassezia yeasts are normal flora of the skin that are discovered in 75~98% of health subjects, but since its association with various skin disorders have been known, many studies have been conducted in the distribution of the yeasts. OBJECTIVE To isolate, identify, and classify Malassezia yeasts from the normal human skin of Koreans by using the rapid and accurate molecular biology method (26S rDNA PCR-RFLP) which overcome the limits of morphological and biochemical methods, and to gather a basic database that will show its relation to various skin diseases. METHODS Malassezia yeasts were cultured from clinically healthy human skin using scrub-wash technique at five sites (forehead, cheek, chest, upper arm, and thigh) and swabbing technique at scalp in 160 participants comprised of 80 males and 80 females aged from 0 to 80. Identification of obtained strains were placed into the one of the 11 species by 26S rDNA PCR-RFLP. RESULTS An overall positive culture rate was 62.4% (599/960). As shown in the experiment groups by their age, the positive culture rate was the highest (74.2%) in the age 21~30 and 31~40 (89/120). In the experiment groups by different body areas, the scalp showed the highest positive culture rate of 90% (144/160). On analysis of 26S rDNA PCR-RFLP, M. globosa was the most predominant species in the age 0~10 (32.8%), 11~20 (28.9%), 21~30 (32.3%). M. restricta was identified as predominant species in the age 41~50 (27.9%), 61~70 (31.5%) and 71~80 (24.0%). In the age 31~40 years, M. sympodialis was found to be the most common species (24.6%). According to body site, M. restricta was more frequently recovered in the scalp (56.8%), forehead (39.8%) and cheek (24.0%) and while M. globosa was more frequently recovered in the chest (36.8%). Higher positive culture rates of Malassezia yeasts were shown in male subjects than female counterparts in all body areas except scalp (p<0.05). Especially in this study, M. dermatis, newly isolated Malassezia species from atopic dermatitis patient in Japan, was isolated and identified in 19 cases (1.9%) in healthy subjects. CONCLUSION The key is to recognize the existence of a difference in the type of Malassezia species in different ages as well as body areas, which reflects differing skin lipid levels in various ages and different body areas. Moreover, 26S rDNA PCR-RFLP analysis which was opted in this study could provide a sensitive and rapid identification system for Malassezia species, which may be applied to epidemiological surveys and clinical practice.

Abstract
BACKGROUND Confluent and reticulate papillomatosis of Gougerot and Carteaud is a rare entity and a subject of controversy in terms of nosology. It has occasionally been regarded as a peculiar variant of acanthosis nigricans, pityriasis versicolor or amyloidosis. OBJECTIVES To discuss confluent and reticulate papillomatosis and its diagnostic criteria as a distinct entity. METHODS Retrospective study from 1994 to 2005 based on photographic files from 2 dermatology wards at the Saint Louis Hospital, Paris. Files containing a precise clinical description of the rash and at least one mycological element were included. RESULTS Nine cases were included (6 females, 3 males). These patients showed clinical features comprising elementary lesion, distribution and topography corresponding to the classical description; histology was also consistent with confluent and reticulate papillomatosis, with no signs of amylosis and negative fungal samples or failure of antifungal treatment. One patient was presenting associated acanthosis nigricans. Doxycycline was efficacious in 4 cases in which it was evaluated. CONCLUSION Confluent and reticulate papillomatosis is a definite entity and is not a superficial fungal disease. It must be distinguished from pityriasis versicolor as well as acanthosis nigricans and cutaneous amyloidosis. The therapeutic efficacy of oral cyclines (doxycycline or minocycline) appears to be an important distinguishing feature that can serve as a diagnostic criterion.

Abstract
Confluent and reticulated papillomatosis (CARP) was first described >60 years ago. It is distinct from acanthosis nigricans. This article presents the results of a review of the literature in MEDLINE through May 2006 using the terms 'confluent and reticulated papillomatosis', 'reticulated and confluent papillomatosis of Gougerot and Carteaud', and 'reticulated papillomatosis'. A recent report has linked the presence of Dietzia spp. (family: Dietziaceae; suborder: Corynebacterineae; order: Actinomycetales) in the skin to CARP. CARP has also been linked to defects in keratinization. Other possible causes of CARP that have been suggested but seem less likely include endocrine abnormalities, Pityrosporum, a reaction to UV light, and a variation of cutaneous amyloidosis. CARP has been reported worldwide and occurs in both sexes, all age groups, and all races. The disorder can initially manifest as hyperkeratotic or verrucous papules that coalesce to form a reticular pattern peripherally and confluent plaques centrally. Although a variety of treatments for CARP exist, oral minocycline 50-100mg twice daily has been the preferred treatment. However, recent reports of the effectiveness of azithromycin 250-500mg three times weekly may make azithromycin the preferred treatment for CARP, since it has a more benign adverse effect profile than minocycline. Other effective antibacterial treatments include fusidic acid 1000mg daily, clarithromycin 500mg daily, erythromycin 1000mg daily, tetracycline 500mg twice daily, and cefdinir 300mg twice daily. If a recent finding that CARP is caused by a bacterial microorganism is replicated, treatment should likely be determined by bacterial sensitivities, antibacterial adverse effect profiles, and cost considerations. Other oral treatments of CARP that are effective but currently disfavored because of the effectiveness of minocycline include isotretinoin, acitretin, and etretinate. There have been mixed reports regarding the effectiveness of topical treatments, which include selenium sulfide, ketoconazole cream, tretinoin, tazarotene, tacalcitol, and calcipotriene (calcipotriol).

Abstract
BACKGROUND Confluent and reticulate papillomatosis (CRP) (Gougerot-Carteaud syndrome) is a disorder that has been characterized in only small cohorts of patients. OBJECTIVES Better to characterize the clinical and pathological findings of the disorder. METHODS We retrospectively reviewed the clinical presentation, response to treatment and histological findings of patients presenting to Mayo Clinic (Rochester, MN, U.S.A.) with CRP. RESULTS The disorder was diagnosed in 39 patients between 1972 and 2003. Mean age at onset of the skin eruption was 15 years (range 8-32); 21 patients (54%) were male; most were white; most (33) presented for reasons of cosmesis; and eight described the rash as mildly pruritic. At presentation, the skin eruption had been present for a mean of 3.1 years (range 3 months-20 years) and had been recalcitrant to treatment, including antifungal treatment. Typical objective findings were scaling brown macules and patches and velvety papules and plaques, reticulated and papillomatous at least in part, involving the upper trunk, axillae and neck. The most frequent initial diagnostic impressions were tinea versicolor, acanthosis nigricans and CRP. Scales in 32 cases were examined with potassium hydroxide: eight (25%) showed hyphae, and 24 (75%) did not. Skin biopsy specimens from 21 patients showed variable degrees of hyperkeratosis, acanthosis and papillomatosis. Minocycline was prescribed for 22 patients, of whom 14 of 18 (78%) had complete clearing of the skin eruption and four (22%) a partial response. The skin eruptions recurred after stopping treatment in six patients. CONCLUSIONS CRP occurs predominantly in young adults and teenagers, with cosmetically displeasing brown scaling patches and plaques affecting the neck, upper trunk and axillae. Frequently, the diagnosis is delayed and the disorder not recognized by physicians, including dermatologists. Clinically, the eruption is most often confused with tinea versicolor. Potassium hydroxide staining of the scale is negative in the majority of cases, implying that fungi are not involved in the pathogenesis of this condition, as has been previously proposed. It is important to recognize this disorder, because minocycline therapy is highly effective in most patients. Criteria for the diagnosis are proposed.

Abstract
We describe three teenage siblings with confluent and reticulated papillomatosis, all presenting during a 6-month period. Two of the three patients had confirmed tinea versicolor, with positive potassium hydroxide scrapings, in association with this entity. This is the largest series of siblings with confluent and reticulated papillomatosis, and the only report describing family members having both confluent and reticulated papillomatosis and tinea versicolor. This report lends further evidence to the hypothesis that confluent and reticulated papillomatosis may be etiologically linked to tinea versicolor, and also suggests a genetic predisposition for it.
