Tinea faciei on the right eyebrow caused by Trichophyton interdigitale

Abstract Tinea faciei is a relatively uncommon dermatophyte infection entailing atypical clinical symptoms, usually misdiagnosed and treated with corticosteroids. The authors describe a case of tinea faciei on the right eyebrow caused by Trichophyton interdigitale. The patient was an 18-year-old girl, who had an inflammatory plaque with a scaly, pustular surface on the right eyebrow and upper eyelid, which had persisted for over 1 month. She was once misdiagnosed as having eczema and was treated using corticosteroid cream. A diagnosis of tinea faciei was made based on direct microscopy and culture. The sequencing of the nuclear ribosomal ITS region and β-tubulin gene of the isolate established its T. interdigitale lineage. The patient was cured by treatment with systemic terbinafine in combination with topical application of 1% naftifine-0.25% ketaconazole cream for 2 weeks.

Oral treatment with valacyclovir for HSV-2-associated eczema herpeticum in a 9-month-old infant: A case report.

BACKGROUND: Eczema herpeticum is a rare, severe, and disseminated infection of herpes simplex virus in the setting of eczematous skin diseases. METHODS: We experienced a case of this disease in a 9-month-old infant characterized by a sudden onset of monomorphic vesicles on the head, right lower leg, and two hands. The infant has a 7-month history of atopic dermatitis and his condition was initially regarded as a complication of atopic dermatitis and bacterial infection. After treatment of cefoperazone and dexamethasone, the eruptions got worse. The diagnosis of eczema herpeticum was made according to the clinical features and further confirmed by the findings of herpes simplex virus type 2. RESULTS: The infant was cured by oral treatment with valacyclovir. CONCLUSION: The case highlights that the awareness for the sign of eczema herpeticum when diagnosing children with a sudden onset of disseminated vesicles in the setting of chronic skin disease should be increased. Oral valacyclovir may be an effective and convenient treatment option for pediatric outpatients with eczema herpeticum.

Efficacy and safety of itraconazole use in infants.

BACKGROUND: Itraconazole has been used to treat fungal infections, in particular invasive fungal infections in infants or neonates in many countries. DATA SOURCES: Literature search was conducted through Ovid EMBASE, PubMed, ISI Web of Science, CNKI and Google scholarship using the following key words: "pediatric" or "infant" or "neonate" and "fungal infection" in combination with "itraconazole". Based on the literature and our clinical experience, we outline the administration of itraconazole in infants in order to develop evidence-based pharmacotherapy. RESULTS: Of 45 articles on the use of itraconazole in infancy, 13 are related to superficial fungal infections including tinea capitis, sporotrichosis, mucosal fungal infections and opportunistic infections. The other 32 articles are related to systemic fungal infections including candidiasis, aspergillosis, histoplasmosis, zygomycosis, trichosporonosis and opportunistic infections as caused by Myceliophthora thermophila. CONCLUSION: Itraconazole is safe and effective at a dose of 5 mg/kg per day in a short duration of therapy for superficial fungal infections and 10 mg/kg per day for systemic fungal infections in infants. With a good compliance, it is cost-effective in treating infantile fungal infections. The profiles of adverse events induced by itraconazole in infants are similar to those in adults and children.

Tinea faciei on the right eyebrow caused by Trichophyton interdigitale.

Tinea faciei is a relatively uncommon dermatophyte infection entailing atypical clinical symptoms, usually misdiagnosed and treated with corticosteroids. The authors describe a case of tinea faciei on the right eyebrow caused by Trichophyton interdigitale. The patient was an 18-year-old girl, who had an inflammatory plaque with a scaly, pustular surface on the right eyebrow and upper eyelid, which had persisted for over 1 month. She was once misdiagnosed as having eczema and was treated using corticosteroid cream. A diagnosis of tinea faciei was made based on direct microscopy and culture. The sequencing of the nuclear ribosomal ITS region and ß-tubulin gene of the isolate established its T. interdigitale lineage. The patient was cured by treatment with systemic terbinafine in combination with topical application of 1% naftifine-0.25% ketaconazole cream for 2 weeks.

Administration of Oral Itraconazole Capsule with Whole Milk Shows Enhanced Efficacy As Supported by Scanning Electron Microscopy in a Child with Tinea Capitis Due to Microsporum canis.

Although diagnosis and treatment of tinea capitis in children are not difficult, treatment failures are still somewhat common. We report a case of pediatric tinea capitis cured using oral itraconazole administered with whole milk, after prior treatment failure when oral itraconazole was administered with water. This apparent enhanced efficacy in one individual was demonstrated using scanning electron microscopy.

Atypical infantile genital Molluscum contagiosum.

Genital molluscum contagiosum is rare in children. We report a molluscum contagiosum around the vulva and anus of 9-year-old girl, which has atypical presentations and was finally confirmed by histopathological and electron microscopy findings.

Successful treatment of oral itraconazole for infantile hemangiomas: a case series.

Infantile hemangiomas can present a therapeutic challenge to clinicians, especially when associated with severe pain and feeding difficulties. The standard therapeutic management includes corticosteroids and propranolol. However, the clinical response is not always satisfactory. We present six cases of infantile hemangiomas successfully treated with oral itraconazole approximately 5 mg/kg per day. In the first month, the red color of the lesions became a little lighter and the growth of the lesions was controlled in all cases. An obvious clinical improvement was noted in all cases during the 3-month period, with 80-100% improvement in each patient at the end of the treatment, which was judged by both their parents and the dermatologists. Compliance with treatment instructions of oral itraconazole in infants was judged to be very good. Side-effects were mild and limited. Although itraconazole can inhibit angiogenesis and tumor growth in vitro and in vivo associated with some cancers, further research is required to understand the pathogenesis of infantile hemangiomas and the mechanism of itraconazole.

Alternaria arborescens infection in a healthy individual and literature review of cutaneous alternariosis.

A 28-year-old man presented at our clinic with 1-month history of an ulcer covered with crust on his left anterior tibia. Based on the morphological features and molecular identification, the patient was diagnosed as cutaneous alternariosis caused by Alternaria arborescens. He was successfully cured by oral itraconazole and topical use of 0.25% liposomal amphotericin B. A review of published studies revealed 29 cases of cutaneous alternariosis. Most cases (90%) occurred in immunosuppressed patients; itraconazole (59%) and voriconazole (24%) are the most effective treatments of choices.

Scanning and transmission electron microscopic observation of the parasitic form of Trichophyton violaceum in the infected hair from tinea capitis.

Trichophyton violaceum is a pathogen of tinea capitis and usually cause infection of scalp and hair in children. To investigate the parasitic form of T. violaceum in the human hair tissue, the infected hair strands were collected from a 9-year-old boy with tinea capitis due to T. violaceum and observed under both the scanning electron microscope (SEM) and transmission electron microscope (TEM). The SEM and TEM findings revealed that T. violaceum parasitically lives in the hair shaft in various forms and the morphological transformation of the fungus from hyphae into arthrospores was noted. The involved hair shaft was damaged to the great extent and its ultrastructural changes were evident. Those morphological characteristics of T. violaceum and the three-dimensional ultastructure changes of infected hairs give a better knowledge about the host-fungus relationship in tinea capitis.

Microsporum canis infection in three familial cases with tinea capitis and tinea corporis.

We report a familial infection caused by Microsporum canis. The first two patients were a 30-year-old female and her son, a 5-year-old boy, who came in contact with a pet dog at a farm house. The boy then suffered from hair loss for 3 months. There were circular and patchy alopecia with diffuse scaling on his scalp. Meanwhile, his mother also developed patchy erythema and scaling on her face. Several weeks later, the boy's sister, a 4-year-old girl, was noted to have inconspicuous scaly plaques in the center of her scalp. The development of tinea capitis in the two children and tinea corporis in their mother were diagnosed based on the positive KOH examination. Morphologic characteristics and sequencing of the internal transcribed spacers 1 and 2, amplified from primary culture isolates, confirmed that their infections were caused by the zoophilic M. canis. Repetitive sequence-based molecular typing using the DiversiLab system secreted enzymatic activity analysis, and antifungal susceptibility indicated that these isolates might share the same source. The boy and girl were cured by the treatment with oral itraconazole and topical naftifine-ketoconazole cream after washing the hair with 2 % ketoconazole shampoo, and their mother was successfully treated by terbinafine orally in combination with topical application of naftifine-ketoconazole cream.

Impetigo-like tinea faciei around the nostrils caused by Arthroderma vanbreuseghemii identified using polymerase chain reaction-based sequencing of crusts.

We report a case of Arthroderma vanbreuseghemii (a teleomorph of Trichophyton interdigitale) infection around the nostrils in a 3-year-old girl. The culture was negative, so the pathogenic agent was identified using polymerase chain reaction-based sequencing of the crusts taken from the lesion on the nostril. Treatment with oral itraconazole and topical 1% naftifine/0.25% ketoconazole cream after a topical wash with ketoconazole shampoo was effective.

Direct extraction of DNA from positive transparent dressing and swab to identify Candida albicans infection in intertriginous Candidiasis in the inguinal region.

We report a case of a patient infected by Candida albicans which was identified by direct extraction of DNA from a positive transparent dressing and a swab. The patient was a 32-year-old male who complained of erosion in his inguinal region. Large patches of erythema and erosion were present in his inguinal and perianal region, with soya-bean like residue discharge. He was diagnosed with erythrasma and treated with antibiotics but his clinical condition did not improve. KOH examination furnished a positive result for candidiasis. Morphologic characteristics confirmed his infection was caused by Candida albicans. Sequencing of the internal transcribed spacer (ITS) 1/4 polymerase chain reaction products, amplified from positive transparent dressing and cotton swab with discharge and from primary culture isolates, established the Candida albicans lineage. The patient was cured by treatment with itraconazole 200 mg twice a day orally in combination with topical wash with 2 % ketoconazole shampoo and topical use of 1 % naftifine-0.25 % ketoconazole cream.
