Common Clinical Finding

The aim of this study was to isolate and identify dermatomycosis causing dermatophysis in EL- Beida, Libya. In this study  253 cases of skin infection were collected from the dermatology unit at  EL- Thoura hospital in EL- Beida, Libya. These cases clinically diagnosed as superficial mycosis ,130 ( 51.4%) were isolated from males and  123 ( 48.6% )  were females. These cases were classified into 5 groups according to age (1-10, 11-20, 21-31, 31-40 and above 40 year). Our results showed that young ages were more liable to infection than adult. The cases  involved in this investigation represented different occupations. The highest incidence was recorded between school children 40.3 %, followed by workers, farmers and others  29.2%, house wives  17.8%  while it was 12.6% among children less than 5 years. Concerning the clinical and mycological finding, it was noticed that 74 (63.8%) cases gave positive culture while the remaining cases were negative. Scalp infection was the most common clinical finding, in this study Tinea capitis was the most frequent  42.8%  cases,  Microsporum canis and Trich ophyton violaceum were the most common fungi isolated. Tinea corporis and Tinea cruris were diagnosed clinically in 68 (26.8%) cases,  24.4% were from  Tinea corporis while the fungus isolated were   Microsporum canis 41% , Epidermophyton floccosum  14% and Tinea cruris with incidence of  0.8% in which Trichophyton  tonsurans was the only fungus isolated . Onychomycosis and Tinea pedis were seen in  3.4% and the most important isolated agents were  Epidermophyton floccosum 50%, followed by  Microsporum canis and Trichophyton rubrum  25% for each.  This study demonstrates that the prevalence of dermatophytoses in EL- Beida cit, was high (47%), and was more common in males than females. The present study has also indicated that tinea capitis was the dominant (43%).

Molecular analysis of dermatophytes (based on PCR fingerprinting) revealed high clonal differentiation between the genus and species. Microsporum canis (zoophilic dermatophyte, belonging to genus Microsporum), responsible for most cases of tinea capitis in children, tinea corporis in adults and dermatophytoses in cats, is very unique in comparison with other dermatophytes. Results of most molecular studies show that there is no clonal differentiation within M. canis as distinct from other species. The aim of this study was application of (GACA)4 repetitive primer and (ACA)5 primer for typing of M. canis strains isolated from human and animals in Central Poland. Fungal strains: 32 clinical isolates of M. canis, originated from patients from Central Poland; 11 strains isolated from infected cats (6) and dogs (7), reference strains of M. canis (CBS 113480), T rubrum (CBS 120358), T mentagrophytes (CBS 120357) and E. floccosum (CBS 970.95). The genomic DNAs of the strains were used as a template in RAPD reaction. No differentiation was observed for the analyzed M. canis strains using (GACA)4 and (ACA)5 typing.

Line Of Therapy

Dermatophytes, the most common causative agents, are assuming high significance in developing countries like India. These organisms metabolise keratin and cause a range of pathologic clinical presentations, including tinea pedis, tinea corporis, tinea cruris, etc. Although usually painless and superficial, these fungi can behave in an invasive manner, causing deeper and disseminated infection and should not be neglected. The lesions may become widespread and may have significant negative social, psychological, and occupational health effects, and can compromise the quality of life significantly. The recent prevalence of dermatophytosis in India ranges from 36.6-78.4%. Currently, dermatologists across India are inundated with cases of dermatophytosis presenting with unusual large lesions, ring within ring lesions, multiple site lesions (tinea cruris et corporis), and corticosteroid modified lesions, making diagnosis a difficult bet. 1 First line of therapy has always been a topical agent; while in resistance of the topical agents next preferred treatment are the oral therapies of antifungal agents (Ketoconazole, Terbinafine, Fluconazole and Itraconazole). However complementary and alternative therapy has also shown the significant results in control of growth of these dermatophytes. Homoeopathy has always been a safe and cost effective treatment in cases of dermatophyte infections.2 The present case report of a 31 years old Muslim female, Sepia officinalis 1M and Sulphur (30C and 200C) have shown marked improvement in the reduction of the lesion. Key words: Tinea corporis, homoeopathy, totality of symptoms, repertorisation.

Tinea capitis is a fungi infection of the scalp that disproportionately affects children in rural and underserved communities in Nigeria. A case-control study was conducted to identify the causative agents and factors that predispose school pupils to tinea capitis in two selected government-owned public primary schools in Osogbo, Southwestern Nigeria. A total of 230 participants were included in the study: 115 cases and 115 controls. Head scrapings were collected from pupils with suspected T. capitis lesions, viewed under Potassium Hydroxide smear microscopy and cultured in Sabouraud’s Dextrose Agar (SDA) for characteristic fungal elements. A total of 105 (91%) samples were successfully cultured, of which 56% (59/105) were from male pupils. Tricophyton rubrum (34%), Tricophyton mentagrophyte (31%) and Microsporum canis (18%) were the most prevalent organisms. Other dermatophytes obtained include Microsporum nanuum (3%), Epidermophyton floccusum (6%), Tricophyton verucosum (1%), and Microsporum gypseum (8%). Pupils between the ages of 4 and 7 years had the highest distribution (67%) followed by those between the ages of 8 and 11 years (39%). Playing with animals, the sharing of combs and not bathing with soap were significantly associated with tinea capitis infection (P < 0.05) in each case. This study showed a high prevalence of tinea capitis caused by the identified dermatophytes in the area.

FUNDAMENTOS: Tinea capitis é importante infecção fúngica de interesse dermatológico e pediátrico. No Brasil sua prevalência é desconhecida, e os agentes causais principais são o Trichophyton tonsurans nas regiões Norte-Nordeste e o Microsporum canis no Sul-Sudeste do país. Conhecimento sobre gênero e espécies mais prevalentes tem importância sanitária e terapêutica. OBJETIVOS: Identificar espécies de dermatófitos, causa de Tinea capitis, em serviço universitário que atende clientela do Sistema Único de Saúde, de procedência urbana e rural, no interior do Estado de São Paulo. MÉTODOS: Amostras de casos clínicos suspeitos de Tinea capitis, procedentes da área de abrangência da Faculdade de Medicina de Botucatu-Unesp, foram investigadas por exame direto e cultivo visando ao diagnóstico e isolamento do agente causal. RESULTADOS: De 1.055 suspeitas, 594 foram confirmadas por exame direto, em 364 (61,1%) isolou-se o agente: M. canis em 88,2%, seguindo-se T. tonsurans (4,7%), T. rubrum (3,3%), M. gypseum (1,9%), T. mentagrophytes (1,6%). O sexo masculino correspondeu a 55,7% dos casos, e a faixa etária entre 0-5 anos predominou com 62,6% (p < 0,05). CONCLUSÕES: A prevalência detectada do M. canis superou o esperado para a Região Sudeste do Brasil. A freqüência de 88,2% pode estar influenciada por pacientes procedentes da zona rural. Esse dado deve ser considerado quando de decisão terapêutica.

Abstract: Dermatophytosis is a disorder of tissues with keratinized ephithelia e. g. stratum corneum of epidermis, hair, and nails, caused by dermatophyte fungi from arthrodermataceae family. This family has more than 40 species divided into three genera: Epidermophyton, Microsporum, and Trichophyton. The distribution of dermatophytosis is based on its location: tinea capitis, tinea barbae, tinea cruris, tinea pedis et manum, tinea unguium, and tinea corporis. This study aimed to obtain the profile of dermatophytosis classified by location, age, gender, job and therapy at the Dermatovenerology Clinic of Prof. Dr. R. D. Kandou Hospital Manado during the period of January-December 2013. The results showed that of 4,099 skin disease cases in 2013, there were 153 (3.7%) cases of dermatophytosis with the most frequent found was tinea cruris (35.3%), the age group was 45-64 years old (32.7%), most patients were female (60.8%), commonly housewife (22.9%), and the most treatmen tused was topical therapy (68.6%).Keywords: dermatophyte, dermatophytosis, tinea Abstrak: Dermatofitosis merupakan penyakit pada jaringan yang mengandung zat tanduk, seperti stratum korneum pada epidermis, rambut dan kuku, yang disebabkan oleh jamur dermatofita dari famili arthrodermataceae.

Este estudo avaliou o potencial de cães e gatos em disseminar fungos dermatófitos, o perfil epidemiológico mais suscetível e as principais síndromes clínicas associados à dermatofitose humana. Foram coletados e cultivados pêlos e escamas de 21 gatos e 33 cães domiciliados com 25 proprietários com diagnóstico de dermatofitose. Tanto crianças como adultos adquiriram a dermatofitose a partir do contato com cães e gatos. A maioria das crianças apresentava Tinea capitis enquanto os adultos apresentavam Tinea corporis. Dos animais avaliados, 67% (36/54) foram positivos para fungos dermatófitos, sendo 95% (20/21) dos gatos e 49% (16/33) dos cães positivos. Dos gatos analisados, tanto assintomáticos como sintomáticos podem ter transmitido a doença. Quanto aos cães, os assintomáticos foram provavelmente os principais veiculadores da dermatofitose aos seus proprietários. Das amostras positivas em gatos, e em 94,4% das positivas em cães, o dermatófito isolado foi o Microsporum canis.

Tinea capitis is more common in children than in adults. Due to the low incidence of this condition among adults, it is frequently misdiagnosed as other scalp diseases, such as seborrheic dermatitis, psoriasis, and cellulitis. Herein, we describe an 82-year-old woman who presented with erythematous scaly patches and alopecia. Mycological examinations revealed tinea capitis caused by Microsporum canis. The patient was then successfully treated with antifungal medications.

Background and Purpose: Dermatophytes as the causative agents of dermatophytosis(ringworm) are widely spread around the world. Accurate identification ofdermatophytes in one area can be particularly important for epidemiological studies.Regarding this, the aim of the present study was to describe the species spectrum ofdermatophytes, isolated from patients in Mashhad city, Iran, using the molecular-basedmethod.Materials and Methods: This study was conducted on 79 dermatophyte isolatesobtained from the human skin, hair, and nail specimens. Species identification wasperformed by the polymerase chain reaction-restriction fragment length polymorphismanalysis of ribosomal DNA internal transcribed spacer regions using MvaI restrictionenzyme.Results: The identified species included Trichophyton mentagrophytes/T. interdigitalespecies complex (n=37, 46.8%), Epidermophyton floccosum (n=12, 15.2%), T. rubrum(n=8, 10.1%), Microsporum canis (n=8, 10.1%), T. violaceum (n=5, 6.3%), T. tonsurans(n=4, 5.1%), Nannizzia gypsea (n=3, 3.8%), T. benhamiae (n=1, 1.3%), and T.verrucosum (n=1, 1.3%). The clinical forms of infection were tinea corporis (n=26,32.8%), tinea cruris (n=22, 27.8%), tinea capitis (n=10, 12.6%), tinea unguium (n=7,9%), tinea manuum (n=6, 8%), tinea pedis (n=5, 6.3%), and tinea faciei (n=3, 3.5%).Conclusion: As the findings indicated, T. mentagrophytes/T. interdigitale speciescomplex had the highest prevalence, and T. benhamiae appeared to be a new emergingagent of dermatophytosis in Mashhad, northeastern Iran.
