..Sporotrichosis is an endemic mycosis in Mexico and Central America...

..The most frequent pathogens were Candida sp. and T. mentagrophytes. It is interesting to note the prevalence of T. cutaneum that has recently been implicated in mycoses of the feet and nails. We did not isolate T. rubrum in any patient...

..Tinea incognito usually resembles neurodermatitis, atopic dermatitis, rosacea, seborrheic dermatitis, lupus erythematosus, or contact dermatitis, and the diagnosis is frequently missed or delayed...

..This contribution provides the clinician with a classification of subcutaneous, systemic, and opportunistic fungal infections...

..Associated malignancies have been found in chronic cases. This case report describes a 72 year-old male with a 30 year history of chromoblastomycosis in the gluteal region, who went on to develop a squamous cell carcinoma...

..Tinea capitis affects mainly children. The frequency and causative organism vary from region to region...

..7%, tinea corporis in 5.2% and tinea cruris in 2.8%. In onychomycosis, the first toe nail was the most commonly affected (58.9%) and the dystrophic type was seen in 50.7% of them...

..Chromoblastomycosis can be refractory to medical treatment. Therapeutic options include oral itraconazole, terbinafine, or 5-fluocytosine, alone or combined with surgery or cryosurgery...

..Itraconazole is considered the treatment of choice, although in some undeveloped countries potassium iodide is still used, owing to its safety and low cost. For systemic or disseminated cases, amphotericin B is the treatment of choice...

..Onychomycosis is multifactorial in origin. Studies have suggested an autosomal dominant pattern of inheritance and human leukocyte antigen DR4 (HLA-DR4) has been shown to protect against onychomycosis in an Ashkenazi Jewish population...

..Whether TNP contributed to the successful outcome cannot be proven but, given the generally poor response of eumycetoma to therapy, we suggest that the role of TNP in the management of this disease merits attention...

..The etiologic agent does not determine the clinical pattern of nail invasion, but superficial onychomycosis is frequently observed; leukonychia and melanonychia can also be clinical manifestations...

..Mucormycosis, a rare opportunistic fungal infection, is re-emerging in importance with the increase in prevalence of immunosuppressive states, both as a result of therapy and disease...

..The isolated Sporothrix schenckii was classified as type 3D according to restriction fragment length polymorphism analysis of the mitochondrial DNA (mtDNA-RFLP)...

..The emergence of drug resistance and high rates of treatment failure with several topical agents makes ivermectin, an antiparasitic drug, an attractive therapeutic option for lice control...

..The long treatment duration, poor therapy response and high rates of relapse have prompted trials of novel antibiotics and antifungals...

..2%) than interdigital (46.7%) infection. In the control group similar results were obtained; patients with OM in 76.5% had plantar mycotic infection and 67.1% interdigital involvement...

..The identification and correction of the underlying aetiology of any chronic wound is the first and most important step to restore wound healing...

..To report a case of simultaneous erythema nodosum and erythema multiforme after local lidocaine injection...

..We report on a 24 year-old female patient with erythema multiforme secondary to Trichophyton mentagrophytes var. mentagrophytes cutaneous infection acquired from contact with animals in a research laboratory...

..Both cases were characterized by long-lasting mycetoma that had previously been failed to be cured and had shown resistance to therapy. However, in our hospital, a multidrug therapy proved to be effective in these cases...

..The majority of patients (75%) benefited with the diagnoses and treatments offered, thus avoiding unnecessary expenses or transportation to urban areas...

..Worldwide recent reports point towards a rising prevalence ofonychomycosis in the pediatric population, especially among adolescents. Dermatophytes are the most common etiologic agents...

..Inflammatory tinea capitis or kerion is the result of a hypersensitivity reaction to a dermatophytic infection. Majocchi's granuloma, in contrast, usually begins as a suppurative folliculitis and culminates in a granulomatous reaction...

..We found no association with occupation, gender, social background or age. DUSG can be used to evaluate the number of parasites per furunculoid lesion avoiding misdiagnoses and treatment delays...

..This survey showed the high frequency of onychomycosis. An intentional search with mycological confirmation is needed in out-patients attending general practice with other complaints, to detect undiagnosed cases...

..An improvement in certain HIV-associated opportunistic infections has been associated with initiation of cART...

..The objective of this study was to determine the concentration of fungi in the air of the intensive care unit (ICU) of "Dr. Manuel Gea González" General Hospital...

..We present a 34 year-old woman with HIV infection with a necrotic primary mucormycosis of the skin associated to a venous catheter. She was treated with amphotericin B and surgical debridement...

..The genetic differentiation among isolates and the dendrogram suggest that the groups of isolates are different. The network of haplotypes demonstrates that the majority of the isolates are grouped according to geographic origin...

..This is one of the youngest patients ever reported with subungueal squamous cell carcinoma, and there is only one more case of pseudo-fibrokeratoma and melanonychia reported as initial skin lesions...

..Imipenem has shown to be effective both in vitro and in vivo against some actinomycetes. Amikacin with Imipenem has a synergistic effect...
