    2013-04-01

    Full Text Available The Koebner phenomenon or isomorphic phenomenon is described in dermatology texts as the production of lesions of the original disease, in clinically uninvolved skin, following trauma. The lesions are located at the site of trauma and evidence of a traumatic causation is the linear arrangement of some of the lesions, such as in the case of lichen planus. Other disorders known to exhibit the Koebner phenomenon include psoriasis and vitiligo. A number of other diseases are associated with the Koebner phenomenon. Pathergy is a phenomenon of pustule production following trauma, which occurs in certain disorders such as Pyoderma gangrenosum and Behçet?s disease. In some disorders such as impetigo and verruca vulgaris, inoculation may give the appearance of the Koebner phenomenon. A case of pityriasis rosea and Koebner phenomenon at the site of routine blood assay is described in this work. This author has not thus far encountered any description of the Koebner reaction in relation to pityriasis rosea in the literature, but, perhaps, with this report, other physicians will be more open to this possibility and actually uncover similar cases.

    A 31-year-old male patient complained of having follicular and brownish red maculopapules along the Blaschko's lines on the right chest for 2 days. On examination, follicular brownish maculopapules were present on the chest with a uniform size of about 3 mm in diameter. The lesions were isolated without a tendency to merge, giving several S-shaped, band-like appearances. Direct mycological examination of the skin flakes revealed many pseudomycelial hyphae and yeast cells with typical spaghetti and meatball appearance. Wood's light examination of the lesion revealed a golden yellow fluorescence. A diagnosis of blaschkoid pityriasis versicolor was suggested because of blaschkoid distribution of the lesions in this new variant of PV.

    Full Text Available Malassezia species are found in part of the normal human cutaneous commensal flora, however it has been known for many years that the Malassezia yeasts are associated with a number of different human diseases ranging from pityriasis versicolor to seborrhoeic dermatitis. In addition, since the 1980s, they have been reported as causing opportunistic systemic infections. The taxonomy of Malassezia spp. has recently been modified to include 13 obligatorily lipophilic species, plus one non-obligatorily lipophilic species, which only rarely colonizes human hosts and currently the genus consist 14 species as M. furfur, M. pachydermatis, M. sympodialis, M. globosa, M. obtusa, M. slooffiae, M. restricta, M. dermatis, M. japonica, M. nana, M. yamatoensis, M. caprae, M. equina, M. cuniculi. Fastidious growth requirements of Malassezia yeasts defied the initial attempts to culture these organisms and their true identification and the relationship between different species only became apparent with the application of modern molecular techniques. The causative fungus is seen especially in such seborrheic areas as the scalp, face, trunk and upper back. Under the influence of various exogenous or endogenous predisposing factors, these yeasts change from the blastospore form to the mycelial form and become pathogenic. Diagnosis of pityriasis versicolor which is caused by Malassezia species is generally easy and lies on the basis of its clinical appearance and can be confirmed by mycological examination. The diagnosisis is mainly based on direct examination with potassium hydroxide (KOH and demonstration that represents pseudohyphae and blastoconidia as the typical %u201Cspaghetti and meatballs%u201D pattern. Characteristic features of the genus Malassezia include a distinctive morphology and an affinity for lipids in culture. Culture is necessary to recover the infecting strain, especially for epidemiologic purposes and also to test its antifungal susceptibility

    Full Text Available Pityriasis versicolor is a superficial fungal infection caused by mycelial form of Malassezia spp, which is confined to stratum corneum. It usually present in the trunk as either hypo or hyperpigmented, aymptomatic, round to oval macules of varying sizes, which may merged to form geographic shape. Diagnosis is usually done clinically, or KOH examination which shows typical spagetti and meat balls appearances, or even by wood’s lamp which shows orange to yellow fluorescence. The case series had been recording in between 2012 to 2013. Within that period, we had recorded 32 cases. All the patients which we had recorded presented with multiple, asymptomatic macules of small sizes varying from 1-2 cm in diameter to 3-4mm in diameter, usually round to oval, hypopigmented, non scaly lesions. 26 patients had lesions on forearms, 3 patients had lesions on dorsa of hands bilaterally, 3 patients had similar kind of lesions on thigh. Besnier’s test was positive in 14 (43.75% patients. KOH examinations showed fungal hyphae in 14 (33.33% patients with typical spagetti and meat balls appearances in 9 (8.13% patients. All of them were given and all of them got response and healed within 2-4 months.

    Full Text Available The article deals with clinical diagnosis and treatment of pityriasis rubra pilaris (PRP. The authors analyze the diagnostic errors, present literature review, and their own observations. The clinical study included 23 patients with pityriasis rubra pilaris: 18 women and 5 men, average age of 54 ± 7.2. The clinical diagnosis of all examined patients was subsequently confirmed by histological analysis of the skin. The primary clinical diagnosis was psoriasis in 15 (65.2% patients, 6 (26% patients received treatment for toxic exanthema, and only 2 (8.8% patients were presumptively diagnosed with pityriasis rubra pilaris. In conclusion, pityriasis rubra pilaris was initially misdiagnosed in 91.2% of patients. Considering the great number of diagnostic errors, we analyzed the main diagnostic and differential diagnostic features of PRP. The most effective of all synthetic retinoids in PRP treatment is acitretin. Although symptomatic improvement in PRP occurs within a month, substantial improvement, even clearing is possible within 4 - 6 months.

    Full Text Available Background: Pityriasis rosea is a common, acute exanthem of uncertain etiology. The exact cause of pityriasis rosea is not known but various hypotheses have been postulated incriminating infective agents such as viruses, bacteria, spirochete and noninfective etiologies such as atopy and autoimmune causes have also been investigated. Aim: We undertook a study to investigate the role of Streptococcus haemolyticus in the causation of pityriasis rosea and study the levels of C-reactive protein (CRP and ASLO titer in patients with pityriasis rosea. Materials and Methods: The study included 20 patients with pityriasis rosea attending the outpatient dermatology department at JIPMER hospital during the period from June to December 2004. Corresponding number of age- and sex-matched controls were chosen from amongst healthy individuals and patients attending skin OPD with dermatological disorders other than pityriasis rosea. Results: On analyzing the data collected from 20 cases of pityriasis rosea, the average age was found to be 15.3 years and ranged from 5 years to 30 years. The male to female ratio was found to be 1.5:1. The average duration of illness was 14.5 days (median and 29.3 days (mean. CRP was negative in all the cases as well as the controls. ASLO titer was found to be raised in 2 (10% cases, while it remained below the critical value in all the controls. On comparing the cases and controls, the raised ASLO titer in the cases was found to be not statistically significant (p = 0.147. From the throat swab culture, Streptococcus haemolyticus was isolated from only one case and none of the controls. This finding was not statistically significant (p = 0.310. Conclusion: As per the findings of the present study, we arrived at conclusion that there is no association between streptococcus pharyngitis and pityriasis rosea.

    Full Text Available Pityriasis rubra pilaris (PRP is an uncommon idiopathic papulosqamous disorder characterized by circumscribed follicular keratosis, palmoplantar keratoderma and frequently erythroderma. Seven patients of PRP (five females and two males in the age range of 2 to 50 years seen over a 2-year period are presented with their clinical features, triggering factors, associations and laboratory investigations. The clinical type of PRP was adult onset classical variety in three, juvenile circumscribed variety in two and adult onset atypical variety and juvenile classical variety in one each. The triggering factors were upper respiratory tract infection with nutritional deficiencies in two and folliculitis in one. The histopathology was consistent with PRP in all. Four patients were managed with oral vitamin A while one each was put on methotrexate, etretinate and topical steroids and they showed a good response. More number of cases should be studied over a longer period to substantiate the suggested immunologic mechanism of PRP.

    Full Text Available The authors present the results of the systemic application of flukonazole in therapy of Pityriasis versicolor. It was arranged for the total number of 38 patients, 18 females and 20 males. The diagnosis of diseases was established on the base of the clinical examination, the native mycological examination and by the using of Wood lamps. The therapy was passed by the using of 300 mg flukonazole in a single dose, once weekly, during two weeks. The following period amounted to one week after the passed therapy. The therapeutic efficacy was assessed with regard to the clinical and mycological healing. The clinical efficacy was assessed semiquantitative on the base of increasing of the percentage rates of the total score of disease that was computed by collecting of the numeric values for every clinical argument typical for the disease, and the mycological efficacy on the base of the mycological findings and the fluorescence finding after lightening with the Wood's lamp. The controlling examinations were performed on day 0, 14 and 22. The results of investigations have shown that the complete clinical healing was achieved after two weeks of therapy in 94,74%, and the mycological healing in 92,11% patients. The rate of the mycological healing was evaluated after 1 week of following period equal to the rate of the clinical healing and it was also 94,74%. The undesirable effects of the drug applications weren't by any patient.

    The effect of pityriasis rosea (PR) on the outcome of pregnancy has not been previously reported. We sought to investigate the possible impact of PR in pregnant women. In all, 38 women who developed PR during pregnancy were observed. In one of them, who developed PR at 10 weeks' gestation and aborted 2 weeks later, plasma, peripheral blood mononuclear cells, maternal skin, and placental and embryonic tissues were studied by quantitative calibrated real-time polymerase chain reaction for human herpesviruses (HHV)-6 and -7. Controls included plasma from 36 healthy blood donors, plasma and paraffin-embedded tissue sections from 12 patients with other dermatitides, and from placental and embryonic tissues from one woman who presented with a 19-week intrauterine fetal death. Of the 38 women, 9 had a premature delivery and 5 miscarried. In particular, 62% of the women who developed PR within 15 weeks' gestation aborted. Neonatal hypotonia, weak motility, and hyporeactivity were noted in 6 cases. In the patient studied in detail, HHV-6 DNA was detected in plasma, peripheral blood mononuclear cells, skin, and placenta and embryonic tissues, whereas HHV-7 DNA was absent. HHV-6 p41 antigen was detected by immunohistochemistry in skin lesions, placenta, and embryonic tissues. No herpesvirus DNA was detected in plasma and tissues from control subjects. This is a case series study with a small number of patients. PR may be associated with an active HHV-6 infection. In pregnancy, PR may foreshadow premature delivery with neonatal hypotonia and even fetal demise especially if it develops within 15 weeks' gestation.

    Geographical variation in the distribution of Malassezia species associated with pityriasis versicolor (PV) has led to the necessity of studying epidemiological, mycological, and clinical characteristics of PV. To study the epidemiological, mycological, and clinical characteristics of PV in a tertiary care hospital. The study was carried out with a cross-sectional design. Two hundred and sixty-two consecutive PV patients were subjected to detailed history, clinical examination, and investigations. Skin scrapings were processed by direct microscopy and culture. Isolates were identified by phenotypic characteristics and polymerase chain reaction-restriction fragment length polymorphism. Association of Malassezia species with clinical and epidemiological characteristics was studied. Statistical analysis of the data was done using statistical software. Maximum number of PV cases (33.9%) belonged to the age group of 21-30 years with a male preponderance. 61.4% of the patients had a sedentary lifestyle, 70.2% showed the gradual onset of the disease, 51.1% presented with pruritus and in 66.4% of the patients symptoms were continuous. Most commonly involved body site was neck (27.8%), 77.09% of the lesions were bilaterally asymmetrical, 87.4% were macular, and 89.3% were hypopigmented. Malassezia furfur (77.3%) was the predominant species. Sedentary lifestyle (61.4%) and increased sweating (48%) were the most commonly associated predisposing factors. PV is more common in males. Distribution of Malassezia species varies significantly from those reported in other parts of India. M. furfur was the most common species responsible for PV in our region. Hence, further studies are required to evaluate the exact cause of this variation.

    Full Text Available Introduction. Pityriasis lichenoides is a rare, acquired spectrum of skin conditions of an unknown etiology. Case Report. A 28-year-old man presented with recurrent outbreaks of herpes simplex virus associated with the onset of red-to-brown maculopapules located predominantly in trunk in each recurrence. Positive serologies to herpes simplex virus type 2 were detected. Histopathological examination of one of the lesions was consistent with a diagnosis of pityriasis lichenoides chronica. Discussion. Pityriasis lichenoides is a rare cutaneous entity of an unknown cause which includes different clinical presentations. A number of infectious agents have been implicated based on the clustering of multiple outbreaks and elevated serum titers to specific pathogens (human immunodeficiency virus, cytomegalovirus, Epstein-Barr virus, Toxoplasma gondii, and herpes simplex virus. In our patient, resolution of cutaneous lesions coincided with the administration of antiviral drugs and clinical improvement in each genital herpes recurrence. In conclusion, we report a case in which cutaneous lesions of pityriasis lichenoides chronica and a herpes simplex virus-type 2-mediated disease have evolved concomitantly.

    Full Text Available A young man employed in a construction company, presented with cutaneous lesions clinically simulating pityriasis rosea. Satisfactory and complete response to corticosteroids and antihistamines was followed by recurrence. Multiple recurrences within a short span of time arose a suspicion of alternative diagnosis. Site visit helped us to rule out occupational contact dermatitis. Further history taking revealed that he was recently using mustard oil for body massage. Subsequent patch testing confirmed contact hypersensitivity to mustard oil. Avoidance of the contact with mustard oil arrested appearance of further skin lesions. We stress the importance of taking a good history in clinical practice in disclosing a possible contactant.

    Full Text Available Several topical agents have been used for treating Pityriasis versicolor. But the main problem is recurrence. In this study 82 patients with recurrent and/or extensive from of infection were treated with oral Ketoconazole. 200 mg once daily for a maximum of 4 weeks. Seventeen patients have been infected for the first time and sixty five for the several times. The duration of disease in most cases (35.4% were between 1-3 years. Out of 82 studied patients only 60 cases were referred for follow up. The clinical and mycological cure were seen in 54 cases (90% after 15 days therapy. In other 6 patients after 15 days the lesions have not cured completely so the treatment was continued for other 2 weeks, but after that, only one of them referred to the clinic, which treatment extended with topical therapy.

    Full Text Available Background: Macrolides are prescribed in the treatment of pityriasis rosea despite conflicting results of the limited number of studies evaluating their role in its treatment. Aim: A randomized double-blind placebo-controlled trial was conducted to evaluate the effect of azithromycin on the clinical course of pityriasis rosea. Methods: Seventy patients of pityriasis rosea were given either azithromycin (n = 35 or placebo (n = 35 and were followed-up at 2, 4 and 6 weeks. Pruritus was assessed in both groups using the visual analogue scale (VAS . Change in the pityriasis rosea severity score (PRSS and in the VAS were recorded as outcome measures and were compared statistically. Results: The decrease in PRSS from baseline through 2, 4 and 6 weeks within both treatment (P < 0.001 and placebo (P < 0.001 arms was found to be statistically significant; however, this change was not significantly different in the two groups (P = 0.179. Similarly, the decrease in VAS was found to be statistically significant within both groups (P < 0.001; however, the change was comparable between the two groups (P < 0.937. Analysis by Fisher′s exact test did not find a significant difference between the two groups for PRSS and VAS. Conclusion: Azithromycin is not effective in pityriasis rosea and the use of macrolides for this disease should not be encouraged in clinical practice.

Patients Forty-one patients with pityriasis rosea, 564 patients with atopic dermatitis (negative control condition), and 35 patients with scabies (positive control condition). We retrieved all records of patients with pityriasis rosea, atopic dermatitis, or scabies diagnosed in 3 years. We analyzed temporal clustering by a method based on a regression model. The monthly incidence of pityriasis rosea is negatively but insignificantly correlated with mean air temperature (gamma s = -0.41, P =.19) and mean total rainfall (gamma s = -0.34, P =.27). Three statistically significant clusters with 7, 6, and 7 cases were identified (P =.03), occurring in the second coldest month in the year (February), the second hottest month (July), and a temperate month (April), respectively. For atopic dermatitis (negative control condition), the nonclustering regression model was selected by Akaike information criteria. For scabies (positive control condition), 1 cluster of 20 cases was detected (P =.03). Significant temporal clustering independent of seasonal variation occurred in our series of patients with pityriasis rosea. This may be indicative of an infectious cause.

    Pityriasis versicolor is one of the most frequent epidermal mycotic infections in the world, but its atrophic variant is rarely described. The aetiology of the atrophy is still unknown, and two main hypotheses have been formulated, one suggesting a correlation with long-term use of topical steroids and the other a delayed type hypersensitivity to epicutaneous antigens derived from components of the fungus. Atrophic pityriasis versicolor is a benign disease, but needs to be distinguished from other more severe skin diseases manifesting with cutaneous atrophy. The diagnosis can be easily confirmed by direct microscopic observation of the scales soaked in 15% potassium hydroxide, which reveals the typical 'spaghetti and meatball' appearance, or by a skin biopsy in doubtful cases. Here, we describe a case of extensive atrophic pityriasis versicolor occurring in a woman affected by Sjögren's syndrome which completely resolved after topical antifungal treatment. 2017 BMJ Publishing Group Ltd.

    Full Text Available Background: Malassezia is a lipid-dependent yeast known to cause Pityriasis versicolor, a chronic, recurrent superficial infection of skin and present as hypopigmented or hyperpigmented lesions on areas of skin. If not diagnosed and treated, it may lead to disfigurement of the areas involved and also result in deep invasive infections. Aim: The aim of the present study was to identify and speciate Malassezia in patients clinically suspected of having Pityriasis versicolor. Materials and Methods: Total 139 patients suspected of having Pityriasis versicolor were evaluated clinically and diagnosis was done by Wood′s lamp examination, confirmed mycologically by using KOH, cultivation on Sabouraud′s dextrose agar and modified Dixon agar at a tertiary care hospital in Mumbai. The total duration of study was 12 months. Results: Majority of the patients were males (59.71% in the age group of 21-30 years (33.81% who were students (30.21% by profession. The incidence of Malassezia in Pityriasis versicolor was 50.35%. The most common isolate was M. globosa (48.57%, followed by M. furfur (34.28%. Majority of the patients had hypopigmented lesions, with M. globosa as the predominant isolate. Neck was the most common site affected; 88.48% were Wood′s lamp positive of which 56.91% of Malassezia isolates grew on culture. KOH mount was positive in 82.01% of which 61.40% Malassezia isolates grew on culture. Conclusions: The procedure of culture and antifungal testing is required to be performed as different species of Malassezia are involved in Pityriasis versicolor and susceptibility is different among different species. Thus, it would help to prevent recurrences and any systemic complications.

    Full Text Available Background: Pityriasis rosea is an acute disseminated rash of unknown etiology and prolonged duration, characterized by erythematous- squamous plaques. Despite having an ostentatious clinical picture for both the patient and family, it is self-limited and usually resolves without sequelae. Pityriasis rosea is often erroneously diagnosed as mycosis and given unnecessary treatment. Objective: To describe the clinical and demographical features of pity- riasis rosea in a group of Mexican pediatric patients. Patients and methods: Retrospective and descriptive study in which the clinical and demographic features of patients attended at the department of dermatology of the National Institute of Pediatrics with diagnosis of pityriasis rosea within a ten year period were analysed. Results: Thirty patients with pityriasis rosea, with a frequency of 3.6 per 1000 dermatological patients. Pityriasis rosea was more frequent in females with a ratio of 1.5 to 1 and a mean age of 10 years. More than half of the patients (56% had an atypical presentation, and biopsy was mandatory in 7 patients to establish the final diagnosis. Conclusions: The knowledge of the clinical features of pityriasis rosea by primary care physicians will prevent from unnecessary work-up and treatments.

    Full Text Available Abstract Background Pityriasis versicolor is a superficial infection of the stratum corneum which caused by a group of yeasts formerly named pityrosporium. The taxonomy of these lipophilic yeasts has recently been modified and includes seven species referred as Malassezia. The aim of this study is to compare the distribution of Malassezia species isolated from pityriasis versicolor lesions and those isolated from healthy skins. Methods Differentiation of all malassezia species performed using morphological features and physiological test including catalase reaction, Tween assimilation test and splitting of esculin. Results In pityriasis versicolor lesions, the most frequently isolated species was M. globosa (53.3%, followed by M. furfur (25.3%, M. sympodialis(9.3%, M. obtusa (8.1% and M. slooffiae (4.0%. The most frequently isolated species in the skin of healthy individuals were M. globosa, M. sympodialis, M. furfur, M. sloofiae and M. restricta which respectively made up 41.7%, 25.0%, 23.3%, 6.7% and 3.3% of the isolated species. Conclusions According to our data, M. globosa was the most prevalent species in the skin of healthy individuals which recovered only in the yeast form. However, the Mycelial form of M. globosa was isolated as the dominant species from pityriasis versicolor lesions. Therefore, the role of predisposing factors in the conversion of this yeast to mycelium and its subsequent involvement in pityriasis versicolor pathogenicity should be considered.

    Pityriasis rosea is a common skin disease that has been suspected to have a viral etiology. We performed nested polymerase chain reaction to detect human herpesvirus-7, human herpesvirus-6, and cytomegalovirus DNA in lesional skin, nonlesional skin, peripheral blood mononuclear cells, serum, and saliva samples isolated from 14 pityriasis rosea patients. Viral mRNA expression and virion visualization within lesional skin were studied by in situ hybridization and transmission electron microscopy, respectively. By nested polymerase chain reaction, human herpesvirus-7 DNA was present in lesional skin (93%), nonlesional skin (86%), saliva (100%), peripheral blood mononuclear cells (83%), and serum (100%) samples, whereas human herpesvirus-6 DNA was detected in lesional skin (86%), nonlesional skin (79%), saliva (80%), peripheral blood mononuclear cells (83%), and serum (88%) samples. By contrast, cytomegalovirus DNA was not detected in these tissues. Control samples from 12 healthy volunteers and 10 psoriasis patients demonstrated rare positivity for either human herpesvirus-7 or human herpesvirus-6 DNA in skin or serum. By in situ hybridization, infiltrating mononuclear cells expressing human herpesvirus-7 and human herpesvirus-6 mRNA were identified in perivascular and periappendageal areas in 100% and 75% pityriasis rosea skin lesions, respectively, compared to herpesviral mRNA positivity in only 13% normal skin and psoriasis skin controls. Transmission electron microscopy failed to reveal herpesviral virions in pityriasis rosea lesional skin. Nested polymerase chain reaction and in situ hybridization enabled detection of human herpesvirus-7 and human herpesvirus-6 in skin and other tissues isolated from patients with pityriasis rosea. These results suggest that pityriasis rosea is associated with systemic active infection with both human herpesvirus-7 and human herpesvirus-6.

    Full Text Available Imiquimod is an immunomodulator with both antitumor and antiviral properties. It is currently available in two cream formulations as Aldara (imiquimod 5% and the newly approved Zyclara (imiquimod 3.75%. Imiquimod has been associated with localized erythema, crusting, and scaling at the site of application. However, more severe generalized skin eruptions including erythema multiforme, psoriasis, and hyperpigmentation have been described. The newly approved imiquimod 3.75% cream is a presumably safer alternative due to its lower concentration. This paper describes the development of generalized acantholytic pityriasis rubra pilaris after the treatment of an actinic keratosis on the forehead with imiquimod 3.75% cream.

    Full Text Available Background The species of the genus Malassezia are lipophilic and dimorphic yeasts that are regarded as part of the normal flora of the skin of humans and warm-blooded animals. These organisms are the cause of superficial mycosis in humans and other animals, and are common in pityriasis versicolor and seborrheic dermatitis. Objectives The purpose of this study was to determine the frequency of common Malassezia species in patients affected by pityriasis versicolor and seborrheic dermatitis using of the nested PCR method, in the city of Ahvaz. Patients and Methods In the present study, 85 samples from patients with pityriasis versicolor and seborrheic dermatitis were analyzed by the nested-PCR method. During the first stage, the internal transcribed spacer (ITS region from the ribosomal DNA was reproduced using primers ITS4-R and ITS1F-N. During the second stage, the product of the first step was used as DNA and using three special primer pairs, including Mf-F, 5.8SR and M.gl-F, 5.8SR and M.rt-F and M.rt-R, the inner part of the first phase was detected. Results The most common isolate was Malassezia furfur (51.3% followed by M. globosa (35.2% and M. restricta (13.5%. Amongst the 30 patients with seborrheic dermatitis, in 15 cases (65.2% M. restricta, in six cases (26.1% M. globosa and in two cases (8.7% M. furfur was detected and in seven patients no isolate was detected. Conclusions The nested-PCR is a rapid and repeatable method for identification of important Malassezia species and this method is recommended for use on more patients. In addition the most common agents of pityriasis versicolor and seborrheic dermatitis were M. furfur and M. restricta, respectively.

    Full Text Available Background Pityriasis rosea (PR is a common papulosquamous skin disease in which an infective agent may be implicated. Toll-like receptors (TLRs play an important role in immune responses and in the pathophysiology of inflammatory skin diseases. Our aim was to determine the possible roles of TLRs 3, 7, 8, and 9 in the pathogenesis of PR. Methods Twenty-four PR patients and 24 healthy individuals (as controls were included in this case control study. All recruits were subjected to routine laboratory investigations. Biopsies were obtained from one active PR lesion and from healthy skin of controls for the detection of TLR 3, 7, 8, and 9 gene expression using real-time polymerase chain reaction. Results This study included 24 patients (8 females and 16 males with active PR lesions, with a mean age of 28.62 years. Twenty four healthy age- and sex-matched individuals were included as controls (8 females and 16 males, with a mean age of 30.83 years. The results of the routine laboratory tests revealed no significant differences between both groups. Significantly elevated expression of all studied TLRs were detected in PR patients relative to healthy controls (p < .001. Conclusions TLRs 3, 7, 8, and 9 might be involved in the pathogenesis of PR.

    2015-03-01

    Full Text Available Pityriasis rubra pilaris (PRP is an exceptionally rare, chronic inflammatory dermatosis of unknown etiology. Patients classically present with small, follicular keratosis and salmon-colored plaques that begin at the head and neck and slowly progress to widespread erythroderma including the palms and soles. It is difficult to distinguish PRP from other inflammatory dermatoses; however, features that help aid in the diagnosis include ‘islands' of spared skin, orangish hue and typical findings on biopsy. There are no specific guidelines on therapy and treatment options include corticosteroids, vitamin D analogs, retinoids, methotrexate, cyclosporine, azathioprine and tumor necrosis factor alpha antagonists. Unfortunately options are limited for patients when these drugs do not work. We report a case of chronic PRP, refractory to conventional treatment, successfully treated with ustekinumab monotherapy. The patient was treated with 90 mg subcutaneous ustekinumab injections and began to show improvement within only 8 weeks. Long-term control of the disease has been attained without any significant side effects. We report this case to show that ustekinumab can be used as an alternative treatment method for patients with chronic, unremitting PRP. Treatment response is remarkably rapid and the infrequent dosing leads to patient compliance and a significantly improved quality of life.

    Full Text Available Introduction. Pityriasis rosea (PR is an exanthematous disease related to human herpesvirus- (HHV- 6/7 reactivation. The network of mediators involved in recruiting the infiltrating inflammatory cells has never been studied. Object. To investigate the levels of serum cytokines, growth factors, and chemokines in PR and healthy controls in order to elucidate the PR pathogenesis. Materials and Methods. Interleukin- (IL- 1, IL-6, IL-17, interferon- (IFN- γ, tumor necrosis factor- (TNF- α, vascular endothelial growth factor (VEGF, granulocyte colony stimulating factor (G-CSF, and chemokines, CXCL8 (IL-8 and CXCL10 (IP-10, were measured simultaneously by a multiplex assay in early acute PR patients’ sera and healthy controls. Subsequently, sera from PR patients were analysed at 3 different times (0, 15, and 30 days. Results and discussion. Serum levels of IL-17, IFN-γ, VEGF, and IP-10 resulted to be upregulated in PR patients compared to controls. IL-17 has a key role in host defense against pathogens stimulating the release of proinflammatory cytokines/chemokines. IFN-γ has a direct antiviral activity promoting NK cells and virus specific T cells cytotoxicity. VEGF stimulates vasculogenesis and angiogenesis. IP-10 can induce chemotaxis, apoptosis, cell growth, and angiogenesis. Conclusions. Our findings suggest that these inflammatory mediators may modulate PR pathogenesis in synergistic manner.

    Full Text Available Purpose: Pityriasis versicolor (PV is a chronic superficial fungal disease caused by Malassezia species. Our aim was to identify Malassezia species from PV patients and healthy individuals in Punjab. Materials and Methods: Modified Dixon agar was used as isolation culture medium. Identification was based on morphological observation and biochemical evaluation. The biochemical evaluation consisted of culture onto Sabouraud dextrose agar, catalase reaction, Tween assimilation, Cremophor EL assimilation, splitting of esculin and growth at 38 0 C. Results: Out of 58 microscopically diagnosed cases of PV, growth was obtained from 54 (93.10% cases. The most frequently isolated species were M. globosa, M. sympodialis and M. furfur which made up 51.79%, 31.42% and 18.51% of the isolated etiological agents respectively. However, the major isolate from the back of healthy individuals was M. sympodialis (47.61%, followed by M.obtusa (19.04%, M. globosa (14.20%, M. furfur (9.52%, M. pachydermatis (4.76% and M. slooffiae (4.76%. Conclusions: M. globosa in its mycelial phase was the main etiological agent, but as normal flora from the back of healthy subjects, it was found in significantly less number (P = 0.01, suggesting that the higher pathogenicity of M. globosa in terms of enzymatic endowment, might be the cause of its predominance in PV lesions.

    2015-01-01

    The mycological study of pityriasis versicolor is usually done by potassium hydroxide (KOH) mount and culture. However, KOH mount lacks a color contrast and requires a trained eye to interpret, while culture is difficult to perform, time consuming and has low sensitivity. Chicago Sky Blue 6B (CSB) is a new contrast stain that highlights the fungal hyphae and spores, blue against a purplish background. This study was done to compare the utility of a novel contrast stain (CSB stain) with KOH mount and culture. Skin scrapings from the lesions of 100 clinically diagnosed cases of P. versicolor were subjected to (1) KOH mount and CSB stain for direct microscopic examination and (2) culture using Sabouraud's dextrose agar. The statistical analysis of CSB stain and culture was done using KOH mount as the reference method, as it is the most commonly performed and practical diagnostic test available for P. versicolor. An interrater reliability analysis using the Cohen's Kappa statistic was performed to determine consistency (agreement) among the different modalities. Direct microscopy with CSB stain, KOH mount and mycological culture showed positive results in 98 (98%), 92 (92%) and 56 (56%) patients, respectively. Using KOH mount as the reference method, CSB stain had a sensitivity of 100% which was significantly higher than culture (60.9%). Statistically significant fair agreement was found between CSB stain and KOH mount (94% with κ=0.38, P < 0.001). Negligible agreement was found between CSB stain and culture (66%, κ=0.199, P = 0.001) as well as between KOH mount and culture (64%, κ=0.051, P = 0.107). CSB staining of skin scrapings is the most sensitive method for the diagnosis of pityriasis versicolor. Due to the distinct contrast provided by CSB, it is easy to perform, rapid and qualitatively superior to KOH mount.

    Full Text Available Background: The mycological study of pityriasis versicolor is usually done by potassium hydroxide (KOH mount and culture. However, KOH mount lacks a color contrast and requires a trained eye to interpret, while culture is difficult to perform, time consuming and has low sensitivity. Chicago Sky Blue 6B (CSB is a new contrast stain that highlights the fungal hyphae and spores, blue against a purplish background. Aims and Objectives: This study was done to compare the utility of a novel contrast stain (CSB stain with KOH mount and culture. Materials and Methods: Skin scrapings from the lesions of 100 clinically diagnosed cases of P. versicolor were subjected to (1 KOH mount and CSB stain for direct microscopic examination and (2 culture using Sabouraud′s dextrose agar. The statistical analysis of CSB stain and culture was done using KOH mount as the reference method, as it is the most commonly performed and practical diagnostic test available for P. versicolor. An interrater reliability analysis using the Cohen′s Kappa statistic was performed to determine consistency (agreement among the different modalities. Observations and Results: Direct microscopy with CSB stain, KOH mount and mycological culture showed positive results in 98 (98%, 92 (92% and 56 (56% patients, respectively.

    Full Text Available Several exanthems including Gianotti-Crosti syndrome, pityriasis rosea, asymmetrical periflexural exanthem, eruptive pseudoangiomatosis, and papular-purpuric gloves and socks syndrome are suspected to be caused by viruses. These viruses are potentially dangerous. Gianotti-Crosti syndrome is related to hepatitis B virus infection which is the commonest cause of hepatocellular carcinoma, and Epstein-Barr virus infection which is related to nasopharyngeal carcinoma. Pityriasis rosea has been suspected to be related to human herpesvirus 7 and 8 infections, with the significance of the former still largely unknown, and the latter being a known cause of Kaposi’s sarcoma. Papular-purpuric gloves and socks syndrome is significantly associated with human B19 erythrovirus infection which can lead to aplastic anemia in individuals with congenital hemoglobinopathies, and when transmitted to pregnant women, can cause spontaneous abortions and congenital anomalies. With viral DNA sequence detection technologies, false positive results are common. We can no longer apply Koch’s postulates to establish causeeffect relationships. Biological properties of some viruses including lifelong latent infection, asymptomatic shedding, and endogenous reactivation render virological results on various body tissues difficult to interpret. We might not be able to confirm or refute viral causes for these rashes in the near future. Owing to the relatively small number of patients, virological and epidemiology studies, and treatment trials usually recruit few study and control subjects. This leads to low statistical powers and thus results have little clinical significance.

    Full Text Available Long-term therapy with the macrolide antibiotic erythromycin was shown to alter the clinical course of diffuse panbronchiolitis in the late 1980s. Since that time, macrolides have been found to have a large number of anti-inflammatory properties in addition to being antimicrobials. These observations provided the rationale for many studies performed to assess the usefulness of macrolides in other inflammatory diseases including skin and hair disorders, such as rosacea, psoriasis, pityriasis rosea, alopecia areata, bullous pemphigoid, and pityriasis lichenoides. This paper summarizes a collection of clinical studies and case reports dealing with the potential benefits of macrolides antibiotics in the treatment of selected dermatoses which have primarily been classified as noninfectious and demonstrating their potential for being disease-modifying agents.

    Amyloidosis maculosa is a clinical entity with low incidence factor in our medium, which basically affects middle-aged women. The lesion is characterised by the presence of poorly defined, hyperpigmented, brownish or greyish maculae that converge and focus basically on the upper back and shoulders, usually accompanied by pruritus. Three patients were erroneously catalogued for years as having pityriasis versicolor. Two of these patients presented a typical clinical amyloidosis maculosa, and the third presented a less common manifestation of the disease: a single, well-defined lesion in the subscapular region. We believe that the approach to the diagnosis of pityriasis versicolor with hyperpigmented lesions that do not respond to specific treatment should be revised. Although amyloidosis maculosa has a low incidence in our medium, it is an entity which should not be discarded in these cases.

    Full Text Available Background and Design: Pediatric dermatology is characterized by skin disorders which have frequencies different from those in adults. Skin biopsies are necessary for differential diagnosis and clinicopathologic correlation is very important. The aim of this study was to evaluate retrospectively the pediatric dermatology cases in whom biopsy was performed for differential diagnosis and to investigate the contribution of biopsy to diagnosis of skin disorders. Material and Methods: The cases from whom biopsy was taken in the pediatric dermatology clinic during a three-year period were evaluated retrospectively for pre-diagnoses, biopsy diagnoses, and success of biopsies.Results: Two hundred thirteen (1.7% skin biopsies had been taken from a total of 12420 patients. Henoch-Schönlein purpura, psoriasis, pityriasis lichenoides, pityriasis rosea, lichen planus, pityriasis rubra pilaris, erythema multiforme, atopic dermatitis, granuloma annulare, and pigmented purpuric dermatosis were the most frequent skin disorders diagnosed dermatopathologically. In a total of 120 (56.3% cases, the biopsy diagnosis was within the pre-diagnosis and a biopsy consistency was present. In 25 (11.7% cases, biopsy had no contribution to the differential diagnosis. An absolutely different diagnosis which was incompatible with the pre-diagnosis had been reported in 10 (4.6% cases. Conclusion: In pediatric dermatology, skin biopsy is very helpful for the differential diagnosis. An easy biopsy procedure for the patient, an effective designation of biopsy indication, a good dermatopathologic correlation and an experienced team of pediatric dermatopathology increase the success of skin biopsies.

    Human herpesvirus 7 in pityriasis rosea, this and other viruses in papular-purpuric gloves-and-socks syndrome have been implicated, but their primary or recurrent infections are still in question. In one available blood sample, therefore, IgM, IgG and its high avidity fraction characteristic for recurrent infections were quantitated by indirect immunofluorescence. Peripheral lymphocytes were subjected to nested polymerase chain reaction to detect viral DNA, or cocultivated with several cell cultures. One third of 33 pityriasis rosea patients had elevated IgM, another third had elevated IgG without high avidity molecules to human herpesvirus 7 suggesting primary infection. Thirty percent of controls, more than half of the patients had virtual DNA in their lymphocytes, but only one in 5 skin biopsy specimens were PCR positive. All three co-cultivation attempts yielded viruses extremely rapidly, verified by electron microscopy, polymerase chain reaction and monoclonal antibodies as human herpesvirus 7. These are the first isolates in the geographical regions of Hungary. These data suggest that pityriasis rosea is the consequence of a primary human herpesvirus 7 infection in seronegative adults, and only occasionally is due to virus reactivation. One patient with gloves-and-socks syndrome had an acute, another patient had a persistent coinfection with human herpesvirus 7 and parvovirus B19, two others had a primary herpesvirus 7 infection. Interestingly, this disease might be elicited by both viruses individually or in synergism. Neither human herpesvirus 7 nor parvovirus B19 infect skin cells, but both can be detected in the infiltrating lymphocytes of skin eruptions, in which they induce an altered mediator production, that might be responsible for the general and local symptoms.

    Full Text Available Today is known that genus Malassezia includes seven species: M. furfur, M. sympodialis, M. obtusa, M. globosa, M. restricta, M. slooffiae and M. pachydermatis, but role of each of the species in the pathogenesis of desease has not been eluciated yet, so futher laboratory isolation and identification are necessary. We report the first case of isolation of Malassezia globosa in Serbia (Belgrade, in a patient suffering from Pityriasis versicolor. Identification of M. globosa was based on macroscopic, microscopic and biochemical characteristics. Isolation was done on Leeming and Notman medium and on mDixona agar, at 350C, during 7 days in aerobic conditions. Also the yeast's biochemical phenotype was determined as catalase (+, lipase (+, esculin degradation (-, Tween (20,40, 60 and 80 asimilation (-. M. globosa is a lipophilic yeast of the genus Malassezia and the common member of the skin flora. In concordance with some predis-poning factors M. globosa is implicated in the pathogenesis of several skin diseases (pityriasis versicolor, malassezia foliculitis sebor-rheic dermatitis and some forms of atopic dermatitis. In immuno-compromised patients and neonates this yeast can even cause fatal systemic infections. Because the role of Malassezia spp. in pathogenesis of skin desease is not still determined, we suggest laboratory diagnosis and identification of these species as a routine diagnostic procedure.

    Full Text Available BACKGROUND Papulosquamous lesions form the largest group of skin diseases. Since, they are all characterized by scaling papules or plaques, clinical confusion may result in their diagnosis, hence definitive histopathological analysis is important for their differentiation. MATERIALS AND METHODS The study includes skin biopsies from 108 clinically diagnosed /suspected non-infectious, erythematous, papulosquamous skin diseases which were received in the Department of Pathology, Andhra Medical College, Visakhapatnam for a period of two years from January 2016 to December 2017. The specimens obtained were subjected to formalin fixation and was subjected to routine processing and sections were stained with haematoxylin and eosin (H&E. The lesions were classified as Lichen Planus, Psoriasis, along with rare conditions like Pityriasis Rosea, Parapsoriasis, Pityriasis Rubra Pilaris, Prurigo Nodularis and Lichen Simplex chronicus and clinicopathological correlation was done. RESULTS A total of 108 cases were studied. Lichen planus (51 cases- 47.22% was the most common lesions followed by Psoriasis (34 cases - 31.48% and with majority of cases in the age group of 21 to 30 years (25 cases– 23.15%. Females were more commonly affected with a male to female ratio of 0.89:1. Out of 108 cases, clinicopathological correlation was seen in 68 cases (62.96%. CONCLUSION The importance of specific histopathological diagnosis lies in distinguishing these lesions into different entities as the treatment and prognosis varies widely and is disease-specific.

    Full Text Available During anti-Malassezia screening of plants by CLSI broth microdilution method, Cladia aggregata (Swartz Nyl. (family Cladoniaceae, a fruticose lichen from Sikkim (northeast Himalayan region, has been found effective at minimum inhibitory concentrations (mg/mL of 2.72, 0.63, and 1.28 against yeast-like fungi namely, M. furfur, M. globosa and M. sympodialis, respectively. These test pathogens are responsible for pityriasis versicolor (PV and seborrheic dermatitis (SD in humans. We tried to establish the reason for variable MICs against various Malassezia spp. using bioinformatical tools, thereby reducing the cost of the experimentation. This is the first report on anti-Malassezia activity of C. aggregata and thus can serve as a potential source for the development of cosmaceuticals.

    For many years, the biblical term tzaraat has referred to leprosy. In fact, the disease or diseases described under this name have no relationship to leprosy, as it was known in the Middle Ages or today; moreover, the term referred not only to skin disease, but also to the state of the ritual impurity and punishment for the sins. Although the real nature of tzaraat remains unknown, the differential diagnosis might include the following: Psoriasis, seborrheic dermatitis, favus, dermatophyte infections, nummular dermatitis, atopic dermatitis, pityriasis rosea, crusted scabies, syphilis, impetigo, sycosis barbae, alopecia areata, furuncles, scabies, neurodermatitis, scarlet fever, lupus erythematosus, lichen sclerosus et atrophicus, folliculitis decalvans, morphea, sarcoidosis, and lichen planopilaris. Leprosy became interchangeable with the biblical leprosy due to two inaccurate translations: The Hebrew tzaraat was first translated into Greek as leprosy in the sixth century, and later, the word leprosy was translated into Arabic as lepra in the ninth century.

    443 subjects were examined, 235 applying to the physician due to the occurrence of skin dermatoses (group I) and 208 workers referred for periodic examinations (group II). In group I skin dermatoses were found in 100, i.e. 85%, of the subjects and in group II in 99 i.e. 48% of the subjects. In both groups the most frequent dermatosis was feet skin inflammation, especially interdigital intertrigo. Oil acne was diagnosed in 15, ordinary acne in 23, pityriasis versicolor in 19. erythrasma in 10, and eczema and contact dermatitis in 7 subjects of the first group and 3 subjects of the other group. 204 subjects with feet skin pathologies underwent mycologic examinations and 36 subjects--also bacteriologic examinations. The results of those studies indicate that in 23% of the subjects, feet interdigital intertrigo results from mycologic infections. Bacterial infections may contribute to etiopathogenesis. Imidazole compounds are useful for the treatment and prevention of interdigital intertrigo.

    Acute generalised exanthematous pustulosis (AGEP) is a rare toxicoderma characterised by an acute onset rash, with many sterile pustules on the surface, high fever and increased acute phase reactants. We report the case of a patient who presented to the dermatology department with an AGEP and polyarthritis, in which a novel CARD14 mutation was identified. The pathophysiological mechanism of AGEP remains unclear, although mutations in the IL36RN gene have been identified in a small subset of AGEP patients. Similarly, mutations in the CARD14 gene have been linked to pustular types of psoriasis and familiar cases of pityriasis rubra pilaris; however, there are no reports associating mutations in the CARD14 gene with AGEP. © 2017 The Australasian College of Dermatologists.

    308nm xenon-chloride excimer laser, a novel mode of phototherapy, is an ultraviolet B radiation system consisting of a noble gas and halide. The aim of this systematic review was to investigate the literature and summarize all the experiments, clinical trials and case reports on 308-nm excimer laser in dermatological disorders. 308-nm excimer laser has currently a verified efficacy in treating skin conditions such as vitiligo, psoriasis, atopic dermatitis, alopecia areata, allergic rhinitis, folliculitis, granuloma annulare, lichen planus, mycosis fungoides, palmoplantar pustulosis, pityriasis alba, CD30+ lympho proliferative disorder, leukoderma, prurigo nodularis, localized scleroderma and genital lichen sclerosus. Although the 308-nm excimer laser appears to act as a promising treatment modality in dermatology, further large-scale studies should be undertaken in order to fully affirm its safety profile considering the potential risk, however minimal, of malignancy, it may impose.

    This study was carried out in a textile factory settled in the city center of Adana, Turkey. The workers were evaluated for the presence of superficial mycoses and the interaction of their working environment or working condition. A total of 431 textile workers were included in the study, with a male to female ratio of 378 (87.7%) to 53 (12.3%) and an age range of 19-52 (mean: 33.7 +/- 6.8). Direct examination and/or culture revealed superficial mycoses in 73 (16.9%) workers, among them 56 (76.7%) were classified as dermatophytoses, 8 (11.0%) as Pityriasis versicolor while in nine (12.3%) of the cases, no causative agent could be determined. Trichophyton rubrum (57.1%) and T. mentagrophytes (42.9%) were the two species isolated on culture. This study emphasized that textile workers should be admitted as a risk group for superficial mycoses, especially tinea pedis.

    Full Text Available Context: Psoriasis affects about 1.5% to 3% of world′s population. Other papulosquamous dermatoses are Pityriasis rosea, Lichen planus, Seborrheic dermatitis, Pityriasis rubra pilaris and Parapsoriasis. Drug eruptions, tinea corporis, and secondary syphilis may also have papulosquamous morphology. Because all papulosquamous disorders are characterized by scaling papules, clinical confusion may result during their diagnosis. Separation of each of these becomes important because the treatment and prognosis for each tends to be disease-specific. Aim: To study the pattern of clinical and histopathological features of psoriasis of the skin with clinicopathological correlation. Material and methods: The present study of 42 cases of psoriasis of the skin was carried out in the Department of Pathology of a tertiary care centre from December 2009 to October 2011. In this study, the patients which were clinically diagnosed as psoriasis of skin, before starting the treatment and attending the outdoor skin department were selected. Histopathological findings were interpreted in light of clinical details. Results: Out of 42 cases of psoriasis 24 (57.14% were males, 18 (42.86% were females with male to female ratio of 1.33:1. Mean age was 34.45 years. Maximum number of cases 22 (52.38% were encountered in 3rd and 4th decade of life. Histopathological findings: parakeratosis, acanthosis, suprapapillary thinning, Munro microabscesses and hypogranulosis were noted in most of the cases. Conclusion: Histopathology serves as a diagnostic tool and rules out other lesions which mimic psoriasis. The most accurate diagnosis is the one that most closely correlates with clinical outcome and helps to direct the most appropriate clinical intervention.

    A. sieberi essential oil has been used for treatment of hardly curable infectious ulcers in Middle East Medicine and has been famous due to its wormicide effects. In this review, we evaluated the potency of A. sieberi essential oil in treatment of fungal infections. We searched in PubMed Central, Science direct, Wiley, Springer, SID, and accessible books, reports, thesis. There is a lot of mixed information on chemical compositions of A. sieberi essential oil, but most articles reported α, β-thujones as the main components of essential oils. In vitro studies confirmed the antifungal activity of A. sieberi essential oil against saprophytes fungi, dermatophytes, Malassezia sp. and Candida sp. and these results were confirmed in six clinical studies. The clinical studies confirmed the superiority of A. sieberi essential oil (5%) lotion in improvement of clinical signs of fungal superficial diseases, and mycological laboratory examinations of dermatophytosis and pityriasis versicolor diseases than clotrimazole (1%) topical treatment. The recurrence rate of superficial fungal infections with dermatophytosis and pityriasis versicolor was statistically lower in A. sieberi essential oil (5%) lotion than clotrimazole. There are no adverse effects due to the application of A. sieberi essential oil in clinical studies. Despite, the efficacy of A. sieberi essential oil against Candida sp., there is no clinical study about their related infections. Investigation about the effects of A. sieberi essential oil on fungal virulence factors in order to identifying the exact mechanism of antifungal activity and clinical trials on Candida related diseases are recommended.

  12. The role of L-DOPA on melanization and mycelial production in Malassezia furfur.

    Directory of Open Access Journals (Sweden)

    Sirida Youngchim

    Full Text Available Melanins are synthesized by organisms of all biological kingdoms and comprise a heterogeneous class of natural pigments. Certain of these polymers have been implicated in the pathogenesis of several important human fungal pathogens. This study investigated whether the fungal skin pathogen Malassezia furfur produces melanin or melanin-like compounds. A melanin-binding monoclonal antibody (MAb labelled in vitro cultivated yeast cells of M. furfur. In addition, melanization of Malassezia yeasts and hyphae was detected by anti-melanin MAb in scrapings from patients with pityriasis versicolor. Treatment of Malassezia yeasts with proteolytic enzymes, denaturant and concentrated hot acid yielded dark particles and electron spin resonance spectroscopy revealed that these particles contained a stable free radical compound, consistent with their identification as melanins. Malassezia yeasts required phenolic compounds, such as L-DOPA, in order to synthesize melanin. L-DOPA also triggered hyphal formation in vitro when combined with kojic acid, a tyrosinase inhibitor, in a dose-dependent manner. In this respect, L-DOPA is thought to be an essential substance that is linked to both melanization and yeast-mycelial transformation in M. furfur. In summary, M. furfur can produce melanin or melanin-like compounds in vitro and in vivo, and the DOPA melanin pathway is involved in cell wall melanization.

    Full Text Available Introduction: Skin lesions may be of dermatological importance, affect appearance, and cause problems communicating with peers and may be especially more significant in childhood. Aim :Information on the prevalence of pediatric dermatoses in Western Turkey. This study was aimed to define the existing data. Material and methods : A cross-sectional study was conducted in Canakkale, Turkey, in September-December 2013. It involved 1,957 students from five randomly selected primary and secondary schools. Each student was interviewed for age, gender, and family history, and a dermatologic examination was performed by a dermatologist. Data were coded and analyzed. Results :Of the students, 79.9% revealed at least one dermatosis. The most common disease was benign neoplasms (76%, followed by pigmentary disorders (26.8%, and xerosis (5.8%. In primary schools, the acquired melanocytic nevus, hypopigmented macule, and xerosis; in secondary school the acne was statistically significantly more common. Acne and xerosis was more common in girls, and pityriasis alba was statistically more common in boys. Students who had at least one dermatosis were positively correlated with monthly income. Conclusions :In Turkish school age children, the prevalence of dermatosis is 79.9%. It may be due to not using preventive means for adequate protection from the sun and other environmental factors. Infectious dermatosis and atopic dermatitis are rare and it may depend on the adequacy of public health work.

    Understanding the effects of age on the epidemiology of diseases primarily affecting the skin is important to the practice of dermatology, both for proper allocation of resources and for optimal patient-centered care. To fully appreciate the effect that age may have on the population-based calculations of incidence of diseases primarily affecting the skin in Olmsted County, Minnesota, and worldwide, we performed a review of all relevant Rochester Epidemiology Project-published data and compared them to similar reports in the worldwide English literature. Using the Rochester Epidemiology Project, population-based epidemiologic studies have been performed to estimate the incidence of specific skin diseases over the past 50 years. In older persons (>65 years), nonmelanoma skin cancer, lentigo maligna, herpes zoster, delusional infestation, venous stasis syndrome, venous ulcer, and burning mouth syndrome were more commonly diagnosed. In those younger than 65 years, atypical nevi, psoriatic arthritis, pityriasis rosea, herpes progenitalis, genital warts, alopecia areata, hidradenitis suppurativa, infantile hemangioma, Behçet's disease, and sarcoidosis (isolated cutaneous, with sarcoidosis-specific cutaneous lesions and with erythema nodosum) had a higher incidence. Many of the incidence rates by age group of diseases primarily affecting the skin derived from the Rochester Epidemiology Project were similar to those reported elsewhere. © 2018 The International Society of Dermatology.

    This study sought to determine the prevalence of skin infections and their causative agents in the Libyan population. Samples were collected from 2224 patients attending the Dermatology Clinics of the Tripoli Medical Centre (TMC) between August 1997 and December 1999 and were submitted to a mycology laboratory for analysis. Diagnosis was confirmed by microscopic examination in 1180 cases (53.1%) and the causative agent was isolated and cultured in 1160 cases (52.2%). Dermatophytes, Malassezia furfur and Candida albicans were the most common etiological agents isolated. Tinea corporis accounted for 45.9% of cases (85% of cases occurred in children below 15 years of age). The frequency of the other clinical types in descending order was pityriasis versicolor 27.8% (322 cases), candidiosis 13.4% (156 cases), tinea pedis 8.1% (94 cases), tinea manuum 2.6% (30 cases) and tinea barbae 2.2% (26 cases). Trichophyton violaceum was the most common etiological agent, responsible for 44% (300 cases) of dermatophyte infections. Malassezia furfur was ranked the second most frequent causative agent being found in 27.8% of cases, followed by Trichophyton rubrum 13.8% (160 cases) and Candida albicans 10% (116 cases). Other species isolated included Microsporum canis 8.1% (94 cases), Epidermophyton floccosum 6.6% (76 cases) and Trichophyton mentagrophytes 3.1% (36 cases).

    Dermatophytes are the major cause of superficial mycoses in samples submitted to Clinical Mycology, Glasgow. The most prevalent species is Trichophyton rubrum as identified classically by microscopy and culture. Recent advances in polymerase chain reaction (PCR) technology were examined for the feasibility of introducing a T. rubrum real-time PCR assay into a routine diagnostic service. To improve the diagnostic mycology service by the introduction of a real-time PCR test for T. rubrum. The DNA from 4972 nail and skin samples was obtained using the Qiagen QIAsymphony automated extractor. This DNA was subjected to real-time PCR using T. rubrum-specific primers and a probe. During phase 1 of the study, 862 samples were analysed; 446 of 470 specimens that grew T. rubrum were detected by PCR. Out of 4110 samples analysed during phase 2, 753 T. rubrum infections were diagnosed and reported within 72 h. A total of 3357 samples were negative for a fungal infection by PCR and microscopy; these were also reported within 72 h. A vast reduction in the turnaround times can be achieved using this technique as opposed to classical methods. Samples which are PCR negative but microscopy positive are still subjected to culture. Screening samples for their suitability for PCR prior to processing eliminates the application of PCR for T. rubrum on inappropriate samples such those from the scalp or pityriasis versicolor. © 2011 The Authors.

    Dandruff or pityriasis simplex is a condition of abnormal occurrence of formation of yellowish white scales from the scalp. Many factors play a role in the pathogenesis of dandruff, i.e.colonization of Malassezia species. Examination of Malassezia species previously done by culture as the gold standard. However, there are various difficulties in doing the culture. Identification method with anested-polymerase chain reaction (nested-PCR) is expected to provide quickly and easily detected. This study aimedto determine the diagnostic value of nested-PCR in the identification of Malassezia species in dandruff. From 21 subjects, scales from the scalp were taken and sent to the laboratory for nested-PCR identification. Statistical analysis of diagnostic test carried out to determine sensitivity, specificity, positive predictive value, and negative predictive value. The results showed nested-PCR detected 10 sample (47.6%) positive for Malassezia species consist of M. sympodialis (23.8%); M. slooffiae (9.5%); M. furfur (4.8%); M. globosa and M. furfur (4.8%); and M. restricta and M. sympodialis (4.8%). Detection of Malassezia species by nested-PCR has 100% in sensitivity whereas the specificity was 55%. Nested-PCR test has high sensitivity. Therefore nested-PCR may be considered for a faster and simpler alternative examination in identification for Malassezia species in dandruff.

    Full Text Available Lewandowsky and Lutz dysplasia, also known as epidermodysplasia verruciformis (EV, is an inherited disorder in which there is widespread and persistent infection with human papilloma virus, defect in cell-mediated immunity and propensity for malignant transformation. Differential clinical and histopathologic evolutions of lesions in two cases of familial EV are compared and discussed in detail. Cases were followed up for 7 years. Detailed history, clinical features and investigations, including skin biopsy from different sites at different times, were examined. Generalized pityriasis versicolor like hypopigmented lesions in both the cases, together with variable pigmented nodular actinic keratosis like lesions on sun-exposed areas, were present. Multiple skin biopsies done from various sites on different occasions revealed features typical of EV along with lesions, i.e., actinic keratosis, Bowen′s disease, basal and squamous cell carcinoma, in the elder sibling. However, skin biopsy of the other sibling showed features of EV and seborrheic keratosis only till date. This study reveals that the disease progression is variable among two individuals of the same family. Malignant lesions were seen only on sun-exposed areas and may be associated with other skin lesions or infections such as angiokeratoma of Fordyce and tinea cruris, as seen in this report.

    1982-01-01

    Selective UV-Phototherapy with lambda 300-320 nm (SUP) as well as oral photochemotherapy with 8-methoxy-psoralen plus UVA-radiation (PUVA intern) are very effective in clearing the lesions of the generalized psoriasis and those of the chronic forms of parapsoriasis. Being treated with 4 suberythemal doses per week psoriasis patients are free or nearly free of symptoms after averagely 6.3 weeks of SUP-therapy or after 5.3 weeks of PUVA orally. The PUVA-therapy is mainly indicated in pustular, inverse and erythrodermic psoriasis as well as in parapsoriasis en plaques and variegata. In all other forms of psoriasis and in pityriasis lichenoides-chronica, we prefer the SUP-therapy because of less acute or chronic side effects, and because of its better practicability. X-rays are indicated in psoriais of nails, grenz-rays in superficial psoriatic lesions of the face, the armpits, the genitals and the anal region. (orig.) [de

    Skin infections and infestations are common in a prison environment. The prison is in dynamic equilibrium with the larger society. Hence, it serves as a reservoir of infections which can spread to the larger society. The study sets out to find out how rampant these infections might be in the prison and the factors responsible. Inmates at a Nigerian prison in Ilesha, Osun State, were examined for skin infections. Personal hygiene and living conditions were critically examined. The overall prevalent rate of infectious dermatoses was 49.2% (150/305). There were 178 infections. Dermatophytes accounted for 64%, pityriasis versicolor 27%, bacterial infections 3.4%, and others 5.6%. Only frequency of soap use and accommodation arrangement significantly contributed to the overall prevalence. However, infectious dermatoses were significantly affected by prison status (PP = 0.04), frequency of bath (PP = 0.025), changing of clothing (PP = 0.05), accommodation arrangement (P = 0.0001), frequency of soap usage (P = 0.005), and toilet facility (P = 0.001). The HIV status of the inmates was unknown. Hence, effect of HIV infection cannot be ascertained. Skin infections and infestations are common in prison. A change in living conditions and personal hygiene will definitely help in reducing these infections. © 2012 The International Society of Dermatology.

    Full Text Available BACKGROUND: The skin occupies a powerful position as an organ of communication and plays an important role in socialization throughout life. The interface between dermatology and psychiatry is complex and of clinical importance. AIMS: To document the incidence of cutaneous disorders in patients with primary psychiatric conditions. METHODS: Three hundred patients with a primary psychiatric condition who had cutaneous disease were entered into the study group. The patients were classified appropriately based on the classification of psychocutaneous disorders. The control group included 300 patients presenting with a skin disorder and without any known psychiatric complaint. RESULTS: The majority of the cases in the study group were in the 3rd-5th decade. In this study, the most common primary psychiatric conditions were manic depressive psychosis (53.33%, depression (36.33%, schizophrenia (8.33% and anxiety (2%. Of the study group, 68.66% patients had infective dermatoses and the rest had non-infective dermatoses. A high incidence of pityriasis versicolor and dermatophyte infections was noted in males from the study group. Among non-infective dermatoses, 8% had eczema, and psychogenic skin disorders were seen in 4.67% of the study group. Of these, delusions of parasitosis were the commonest (2% followed by venereophobia (1%. CONCLUSIONS: A statistically significant higher incidence of tinea versicolor and dermatophyte infections was seen in the study group. Delusion of parasitosis was the most common psychogenic skin disorder seen in the study group, followed by venereophobia.

    Actively searching for leprosy, other skin diseases and BCG vaccination scars amongst school children from Agua de Dios, the municipality having the highest prevalence of leprosy in Colombia. A clinical examination of the children was carried out by nurses, interns, general practitioners and experts on leprosy. Skin smear tests and skin biopsies were performed when the clinical findings suggested leprosy. Anti-phenolic glycolipid antibodies in blood were determined in special cases. 86 % of the 2 844 school children were examined; 833 had skin diseases and 16 % of these required evaluation by specialists. Four new cases of paucibacillary leprosy, two indeterminate and two primary polyneuritic cases were found. Pediculosis capitis, pityriasis alba, tinea versicolor, hypopigmented nevus, insect bites and miliaria were frequently detected. BCG vaccination scars were absent in 387 children; following several logistical problems, they were vaccinated. Four children had signs of childhood abuse. An 11-year-old girl presented hypopigmented mycosis fungoides. All diseases and conditions found were treated. The community received information regarding the results, emphasising the importance of an early diagnosis of leprosy. The incidence of leprosy found (16/10,000) was 123 times higher than the rest of the country's incidence. It is advisable to continue clinical examinations in Agua de Dios and research into risk factors for acquiring leprosy.

    Melanins are synthesized by organisms of all biological kingdoms and comprise a heterogeneous class of natural pigments. Certain of these polymers have been implicated in the pathogenesis of several important human fungal pathogens. This study investigated whether the fungal skin pathogen Malassezia furfur produces melanin or melanin-like compounds. A melanin-binding monoclonal antibody (MAb) labelled in vitro cultivated yeast cells of M. furfur. In addition, melanization of Malassezia yeasts and hyphae was detected by anti-melanin MAb in scrapings from patients with pityriasis versicolor. Treatment of Malassezia yeasts with proteolytic enzymes, denaturant and concentrated hot acid yielded dark particles and electron spin resonance spectroscopy revealed that these particles contained a stable free radical compound, consistent with their identification as melanins. Malassezia yeasts required phenolic compounds, such as L-DOPA, in order to synthesize melanin. L-DOPA also triggered hyphal formation in vitro when combined with kojic acid, a tyrosinase inhibitor, in a dose-dependent manner. In this respect, L-DOPA is thought to be an essential substance that is linked to both melanization and yeast-mycelial transformation in M. furfur. In summary, M. furfur can produce melanin or melanin-like compounds in vitro and in vivo, and the DOPA melanin pathway is involved in cell wall melanization. PMID:23762233

    Full Text Available Background: Wong-type dermatomyositis (DM exhibits simultaneous pityriasis rubra pilaris (PRP features. Case Report: A 50-year-old woman presented with a heliotrope rash, Gottron's papules, and a poikilodermic, erythematous rash in shawl distribution without evidence of muscle weakness. Despite topical corticosteroids, the eruption progressed 9 months later to include generalized hyperkeratotic follicular papules, islands of sparing, and atrophic macules with a collarette of scale suggestive of porokeratosis. Mild dysphonia was the only sign of muscle weakness. Serology showed positive ANA. Histopathology revealed interface dermatitis with dermal mucin and melanophages, irregular psoriasiform hyperplasia, alternating mounds of para- and orthokeratosis, and tiers of dyskeratotic cells (columnar dyskeratosis. Systemic corticosteroid therapy was not tolerated; acitretin diminished the hyperkeratosis. While hyperpigmentation persisted, no progression of cutaneous or muscular symptoms has occurred after 22 months of follow-up and cessation of the therapy. Overall, her course did not differ from the natural history documented in the literature review of Wong-type DM. The most similar case also exhibited pseudocornoid lamella changes. Conclusion: Wong-type DM is a clinicopathologic DM-PRP hybrid that can also exhibit porokeratosis-like features best described as columnar dyskeratosis. Recognizing these types of lesions in DM is warranted in order to make an accurate assessment of their prognostic significance.

    Full Text Available There are a lot of works, which are devoted to the study of acne, but these data are often contradictory on the issue of interrelationship and interdependence of clinical manifestations, course and some factors in the pathogenesis of acne and candida infection. Aim of the research was to study the effect of the recommended differentiated therapy on the pathogenetic disorders in patients with acne and concomitant Candida infection. Methods and results. 120 patients with acne were examined. In 100 of them concomitant skin malasseziosis was set in the form of pityriasis rosea, kerosis, comedones, folliculitis, seborrhea, multicolored zoster, with some features, as well as candidiasis. Methods of the research – bacterioscopic, bacteriological, study of skin oiliness and moisture, skin pH, the level of Ca ++, parathyroid hormone and calcitonin. In patients with acne significant shifts in the composition of water-lipid mantle, increased oiliness and decreased moisture of skin, pH changes with a shift to the alkaline side were revealed, the most pronounced – in acne patients with Candida infection. The content of Ca ++ in the organism, as well as parathyroid hormone and calcitonin was increased and also the most indicative it was in patients with acne and concomitant Candida infection. After the comparative analysis on the basis of different levels of clinical and laboratory violations two clinical-therapeutic groups were distinguished, in accordance with that the differentiated therapy offered by us was conducted. Increased oiliness and Рh of skin, decline of moisture before the treatment, especially in patients with III and IV stages of acne, complicated by Candida infection, were normalized after treatment, unlike in patients treated traditionally. Conclusion. After treatment intensity of microbal colonization and also microbal associations of skin was diminished, the level of Ca++, parathyroid hormone and calcitonin went down.

    The objective of the present study was to analyse the occurrence of dermatosis in individuals that had been exposed to cesium{sup 137} during the radioactive accident in Goiania, in 1987 and detect pre-cancerous dermatosis or those predictive of low immunity. The groups were evaluated according to the intensity of radiation they had been exposed to and then compared to a control group of people not exposed to radiation. The population exposed to the cesium{sup 137} was comprised of 109 people, who were divided into Groups I and II, according to the CNEN norms. In group I, 54 people with {<=} 20 rads exposure and/or radio lesion were included; in group II, 55 people with > 20 rads exposure were included, along with the children of group I individuals. This was a historic cohort study, that is, a retrospective study that lasted 9 years, extending from September of 1987 to August, 1996. The presence of the oncoprotein p-53 was studied in the radio lesions of 10 patients. There is no evidence of an increase in the incidence of dermatosis in the exposed groups, excepts for pyoderma in patients with radio lesions. The most frequent dermatosis were: pyoderma, pityriasis versicolor, scabies, dermatophytosis and seborrhoeic dermatitis. The results obtained were not statistically significant for the evaluation of dermatosis predictive of low immunity or precancerous lesions. The oncoprotein p-53 in individuals with radio lesion showed a 80% positivity rate and risk factor estimated in 8 times, for the test. It has proved to be useful because it represents one more option in terms of propaedeutic evaluation and suggests that one should pay close and continuous attention in order to better control the evolution of these individuals.

The best-described adverse effects in the literature are represented by agranulocytosis, myocarditis, sedation, weight gain, hypotension, and drooling; nevertheless, there are other known adverse effects that psychiatrists should readily recognize and manage. This review covers the “rare” and “very rare” known adverse effects of CLZ, which have been accurately described in literature. An extensive search on the basis of predefined criteria was made using CLZ and its combination with adverse effects as keywords in electronic databases. Data show the association between the use of CLZ and uncommon adverse effects, including ischemic colitis, paralytic ileus, hematemesis, gastroesophageal reflux disease, priapism, urinary incontinence, pityriasis rosea, intertriginous erythema, pulmonary thromboembolism, pseudo-pheochromocytoma, periorbital edema, and parotitis, which are influenced by other variables including age, early diagnosis, and previous/current pharmacological therapies. Some of these adverse effects, although unpredictable, are often manageable if promptly recognized and treated. Others are serious and potentially life-threatening. However, an adequate

    Superficial fungal diseases that affect the skin and its appendages are frequently seen in basic triage and in dermatology services. These diseases are distributed in Venezuela with an incidence of 92.9%. The aim of this study was to determine the genera and species that cause dermatomycoses in residents of Anzoátegui state, Venezuela, during the period 2002-2012. A total of 4257 patients with a presumptive diagnosis of superficial mycoses were studied, with ages from 7 months to 79 years. The overall prevalence was 30.9%. The most frequent were dermatophytosis (44.7%). M. canis produced 148 cases of tinea capitis. Three dermatophytic agents represented 95% of all cases, with a significant predominance of T. mentagrophytes with 50%. Candidosis occurred in 28.4%. C. albicans, and the C. parapsilosis complex, were responsible for 80% of the cases. The other species identified were C. tropicalis (n = 41, 11.0%), C. glabrata (n = 10, 2.7%), C. guilliermondii (n = 6, 1.6%), C. krusei (n = 4, 1.1%). Pityriasis versicolor occurred in 22.4% of the cases studied, and less frequently were present onychomycosis produced by a non dermatophytic mold: Fusarium oxysporum (n = 34, 65.4%), Aspergillus terreus (n=16, 30.8%) and Scytalidium dimidiatum (n=2; 3.8%). Rare cases of Trichosporon onychomycosis (0.5%) and one case of black tinea were also found. Health education in the population is recommended to promote measures to prevent transmission of these fungi and prevent the spread of this silent public health problem.

    In 1984 the Venezuelan Work Groups in Mycology (VWGM) were created introducing an innovative approach to the study of the mycoses in Venezuela. To study the occurrence of the mycoses in Venezuela. Review the reported cases of mycoses by the newsletter Boletín Informativo Las Micosis en Venezuela (VWGM) from 1984 to 2010. The data collected showed 36,968 reported cases of superficial mycoses, 1,989 of deep systemic cases, and 822 of localized mycoses. Pityriasis dermatophytosis was the most common superficial infection, and paracoccidioidomycosis and histoplasmosis the most frequent deep systemic infection. Chromoblastomycosis was the most frequently diagnosed subcutaneous infection. The data provided showed the distribution by geographical area for each of the fungal infections studied, which may help to establish the endemic areas. Superficial mycosis is a public health problem due to its high morbidity and is probably responsible for some of the outbreaks in high-risk groups. Paracoccidioidomycosis and histoplasmosis were reported more often, which agrees with earlier reports prior to the formation of the VWGM. Cases of sporotrichosis and chromoblastomycosis in Venezuela can be considered unique due to the high number of cases. This study highlights the contribution of the VWGM to the behavior of the mycoses in Venezuela, its incidence, prevalence, and the recognition of these infections as a problem of public health importance. The VWGM should keep working in this endeavor, not only reporting new cases, but also unifying the clinical and epidemiological criteria, in order to properly monitor the evolving epidemiological changes reported in these types of infections.

    Full Text Available Acitretin, a synthetic retinoid and the active metabolite of etretinate has been increasingly used over the past two decades. It has proved effective in the treatment of many conditions associated with hyperkeratosis and dyskeratosis. A Google scholar search for the use of acitretin in pediatric dermatoses was done using the words “pediatric dermatoses,” “acitretin,” “etretinate,” “systemic retinoids,” “psoriasis,” “pityriasis rubra pilaris,” “ichthyoses,” “disorders of keratinization,” “Darier's disease,” “palmoplantar keratoderma,” “verrucae,” “lichen planus,” “lupus erythematosus,” and “lichen sclerosus.” All the articles were retrieved and classified into review articles, studies, double-blinded trials, and case reports. The final data were then analyzed and presented in a narrative fashion. It has been found that acitretin is useful in a number of pediatric dermatoses. It is preferred over other drugs in pustular psoriasis. Good results can be obtained in various disorders of keratinization, and it may even prove life-saving in conditions like harlequin ichthyosis. However, long-term maintenance therapy is required and exacerbations are known on discontinuing the drug. It can also be used as alternative therapy for many other pediatric dermatoses where the primary treatment has failed. Acitretin should be used even in children for the proper indications. However, proper clinical and laboratory surveillance has to be maintained in patients on long-term acitretin.

    Full Text Available BACKGROUND Skin diseases in pediatric age group are common all over the world. Pediatric dermatoses require separate view from adult dermatoses as there are differences in their clinical presentation and treatment. OBJECTIVE The aim of our study was to determine the prevalence of pediatric dermatoses attending our tertiary care center. MATERIALS AND METHODS This was a cross-sectional study conducted in 100 consecutive children with dermatoses between 5-14 years of age attending dermatology outpatient department at Vinayaka Missions Kirupananda Variyar medical college, Salem. The study was conducted over a period of 6 months from February 2016 to August 2016. Demographic parameters, detailed history, clinical features and diagnosis were recorded and analyzed. RESULTS In our short term study, we examined 100 pediatric cases with 106 dermatoses. The incidence of infections and infestations (43.39% was more prevalent in our study. The most common non-infectious dermatoses in our study was insect bite reactions (17.9%. Dermatitis and eczema (9.39%, disorders of sweat and sebaceous glands (6.6%, pigmentary disorders (5.66%, disorders of hair and nails (3.77%, genetic disorders (2.88%, immune and allergic disorders (2.8%, psoriasis (2.8%, nutritional disorders (0.9%, Polymorphic light eruption (0.9%, pearly penile papule (0.9%, aphthous ulcer (0.9% and pityriasis rosea (0.9% were the other dermatoses seen in the study.CONCLUSION Fungal infections (tinea versicolor and tinea corporis, scabies and insect bite reactions were the common dermatoses observed in our study. Most of the pediatric patients attending our hospital came from rural areas belonging to low socioeconomic strata. Health education, proper sanitation and improved nutrition will help to reduce the incidence of pediatric dermatoses.

    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. 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. 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

    Fungi are schematically responsible for three distinct kinds of infections: superficial mycoses, subcutaneous and deep ones. The current socio-epidemiological transition observed in sub-Saharan Africa does not actually lead to similar consequences regarding these three categories of fungal entities. For instance, it has long been known that superficial mycoses are very prevalent in tropical areas, since they are partly due to the warm climate and the promiscuity. They are mostly caused by dermatophytic fungi or Malassezia sp. (Pityriasis versicolor). Subcutaneous mycoses are rarer, and usually due to dimorphic fungi which are accidentally inoculated into the body after a skin injury or a trauma. Sometimes very spectacular, the clinical outcome is then described as chronic. Thus, chromoblastomycosis, rhinoentomophtoromycosis or mycetoma are some examples of subcutaneous mycoses which remain well-known by practitioners of endemic countries. Deep mycoses (or invasive / systemic mycoses) are defined by fungal infections of deep anatomical sites that should be normally sterile. By contrast with the other entities mentioned above, the outcome may be rapidly fatal for the patient. One of the most outstanding examples was the great increasing of cryptococcal meningitis during the HIV outbreak in the 80'. A few other similar mycoses may be feared in a near future, since they usually occur in contexts of important immunosuppression which are about to be definitely experienced in Africa: overall increase of chronic diseases like diabetes, lengthening life expectancy and its associated diseases, widespread medical practices which were only seen in advanced intensive care units, onco-haematology departments or graft centers so far. Thus, the deep mycoses will inevitably increase in Africa, as they did in all developed countries over the last two decades. The consequences will not only be limited to the clinical management as described above: the diagnostic approach is also

    Full Text Available Abstract Background Although leprosy was eliminated globally in 2000, the disease continues to be the significant cause of peripheral neuropathy, disability and disfigurement in some developing countries. However, recent population-based prevalence data are lacking to inform evidence-based renewed commitment for the final push for leprosy elimination at national and sub-national levels. Methods Community camp-based cross-sectional descriptive study was conducted in four selected districts. World Health Organisation guidelines and tools for leprosy elimination monitoring were used to evaluate the Malawi National Leprosy Programme. Results A total of 6,338 people (60% females, 35% children aged less than 15 years were examined for leprosy and other skin diseases. Prevalence of skin diseases was 18%, the commonest being fungal (9%, eczema/dermatitis (3% and leprosy (1%. Of the fungal skin conditions, pityriasis versicolor and Tinea capatis were the commonest (22% and 21% respectively then Tinea corporis (9%, Tinea cruris (6% and Tinea pedis (2%. A total of 66 leprosy cases were detected out of 6,338 people screened giving a prevalence of 104.1 per 10,000 population (range by district 67.1 to 194.1. Of the leprosy cases, 37 were new, 6 were defaulters and 23 were on treatment, 30 were females and 9 were children aged less than 15 years old. Of the 37 new leprosy cases, 9 (24.3% were children, 25 (67.6% had 1–5 leprosy lesions and 8 (21.6% had grade 2 disability.

    Tinea (pityriasis) versicolor is a superficial fungal infection and one of the most commonly found pigmentary disorders of skin caused by the yeast Malassezia. Multiple topical as well as systemic therapies are available for treatment. Systemic therapies are used for extensive disease, frequent relapse or where topical agents have failed. The aim that translates the rationale of the study was to compare the efficacy, safety, tolerability and cost effectiveness of single dose 400mg versus 7 day 200 mg daily dose of itraconazole in the treatment of tinea versicolor. A clinical study was done to compare the efficacy of single dose (400 mg) of itraconazole and 7 day 200 mg daily dose of itraconazole in the treatment of extensive tinea versicolor. Total 60 patients (aged 18-50 years) were selected for the study during the period of June 2007 to May 2008 in the department of Dermatology of three different hospitals in Bangladesh. Cases having with extensive involvement, diagnosed clinically and confirmed by wood's lamp and KOH microscopy were taken. Patients were randomly allocated into equal groups. Group A was given single dose 400 mg itraconazole and Group B was given 7 day 200 mg daily itraconazole. Fifty three (88%) male and 7(12%) female were included in the study. The mean age of group A was 32.37+/-9 years and in group B 33.23+/-8 years. The mean duration of the disease in group A was 2.63+/-2 months and 2.76+/-2 months in group B. In group A clinical responders was found cure 22(73.33%) and improvement 5(16.33%) and in group B it was found cure 24(79.99%) and improvement 4(13.33%). The measure at the End point (EP1) equals to 90% response and in-group B it was found cure 24 (79.99%) and improvement 4(13.33%). (Here the End point EP2) equals to 93.33%. The EP clinical analysis however shows 91.66% response. Both single dose and 7 day daily dose of itraconazole can be effective in the treatment of tinea versicolor with extensive involvement but single dose appears

    Full Text Available BACKGROUND: The increasing in the number of kidney transplant recipients has favored, more frequently than before, the emergence of dermatoses and warranted their study through subsequent publications. OBJECTIVES: to evaluate the frequency of dermatoses in kidney transplant recipients. METHODS: kidney transplant recipients with suspected dermatoses between March 1st 2009 and June 30th 2010. RESULTS: 53 patients (28 males and 25 females, aged between 22 and 69 (mean age = 45 years were evaluated. Most of them came from the cities of Ceilândia, Samambaia and São Sebastião/DF, and had already been transplanted for 5 to 10 years before (37.7%; 62.3% were recipients of living donors and 83% were prednisone-treated. The most prevalent dermatoses were of fungal (45.3% and viral (39.6% etiologies. Among the non-melanoma malignant neoplasms, the basal cell carcinoma prevailed (six cases, in spite of the low incidence. Concerning fungal dermatoses, 12 cases of onychomycosis, five of pityriasis versicolor and four of pityrosporum folliculitis were reported. For diagnosis, in most cases (64.2%, laboratory examinations (mycological and histopathological were performed. CONCLUSION: cutaneous manifestations in kidney transplant recipients are generally secondary to immunosuppression. The infectious dermatoses, especially those of fungal origin, are frequently found in kidney transplant recipients and their occurrence increases progressively according to the time elapsed from the transplantation, which makes follow-up important. FUNDAMENTOS: o crescente aumento do número dos transplantados renais tem favorecido o aparecimento mais frequente das dermatoses e permitido o estudo em sucessivos trabalhos. OBJETIVOS: avaliar a frequência das dermatoses em pacientes transplantados renais. MÉTODOS: captação de pacientes transplantados renais durante o período de 1° de março de 2009 a 30 de junho de 2010 com suspeita de dermatoses. RESULTADOS : foram

    diseases is likely underreported. Pyoderma vegetans has been noted in 2 cases of HS and 4 cases of Inflammatory Bowel Disease (IBD) and is likely a clue to the linkage of the pathology of IBD and HS. Pityriasis rubra pilaris, in particular Type VI related to HIV, has a relationship more commonly with acne conglobata, but with HS also. Single case reports of diseases associated with HS include systemic lupus erythematosus, acromegaly, Down syndrome, Bazex-Dupre´-Christol, and prurtis ani, but these might be coincidences. Pyogenic Arthritis, Pyoderma gangrenosum, and Acne (PAPA Syndrome) and Pyoderma gangrenosum, Acne, and Suppurative Hidradenitis (PASH Syndrome) are pyodermic-arthritic syndromes that are associated with HS. Erythema nodosum and granulomatous lobular mastitis have been reported with HS but the significance of these reports is uncertain. Because of scarring, HS can result in lymphedema including scrotal elephantiasis and verrucous lymphedema. HS is sometimes accompanied by obesity, hypertension, and anemia and can be considered a disease in the spectrum of metabolic syndrome, a skin disease with systemic consequences. HS, like other types of chronic inflammation when long standing in the perianal and perineal areas, can result in squamous cell cancer. A variety of drugs can induce HS. These include lithium, sirolimus, cyclosporine, vemurafenib, and oral contraceptives. Inverse psoriasis or psoriasis vulgaris as a side effect of infliximab therapy may be associated with HS. These associations aside, most cases of HS occur in isolation without coincident morbidity.
