Antifungal stewardship: What we need to know.

Antimicrobial stewardship refers to a well-coordinated program which promotes the scientific and rational use of antimicrobials, reduces the chances of drug resistance and improves patient outcomes. A comprehensive English language literature search was done across multiple databases (PubMed, EMBASE, MEDLINE and Cochrane) for the period 1990-2022, revealing a large volume of reports of growing resistance to established antifungal therapies, against a backdrop of irrational and unscientific prescriptions. As a result of this, antifungal stewardship, a new kid on the block, has recently garnered attention. This review article is an attempt to summarise the basic concept of stewardship programs, highlighting the dire need to implement the same in the present situation of antifungal resistance and treatment failure.

Clinicomycological Profile of Pediatric Dermatophytoses: An Observational Study.

Background/Objectives: There has been a recent explosion in the incidence of dermatophytic infections globally, especially in tropical countries including India. This increase is associated with a change in the clinical pattern and mycological profile with poor response to treatment, in adults and children. Limited studies in India have focused on pediatric dermatophytoses. Our study's primary objective was to assess the clinicomycological profile of pediatric dermatophytosis in our region and secondarily to understand the association of lifestyle factors with poor response to treatment. Methods: This was an observational study including children ≤16 years of age, clinically diagnosed with tinea. Clinical and lifestyle data regarding site, affected surface area, duration of infection, previous treatment, possible sources of infection, overcrowding, and bathing practices were collected. Samples were collected for potassium hydroxide mount and fungal culture. Results: A total of 183 children participated in our study. The most common diagnosis was tinea corporis. Tinea cruris was more frequent in preadolescents, where males were more affected. Positive associations were seen between increased duration of infection, increased household infection, infection among playmates, irregular bathing, and use of steroid creams. The most common organism isolated was Trichophyton mentagrophytes/interdigitale (55.19%) followed by Trichophyton rubrum (14.75%). Conclusions: There is a change in the mycological profile of pediatric dermatophytosis with an increase in Trichophyton mentagrophytes/interdigitale infection. Important sources of infection in children must be identified in chronic and recurrent cases. Misinformed and ignorant use of steroid creams is an important reason for recurrent infection.

10% Thioglycolic Acid Peel in the Treatment of Pigmented Purpuric Dermatoses: A Pilot Study.

Pigmentary purpuric dermatosis (PPD) is a chronic dyspigmentation characterized by reddish-brown, irregular maculae with dermal hemosiderin deposition, usually affecting the legs. The -SH group in the thioglycolic acid (TGA) strongly binds to iron molecule, solubilizes it, and clears the pigment. We conducted a longitudinal, right-left leg study for assessing the effectiveness and side effects of TGA 10% peel in treating PPD. For preparation of 10% TGA peel, 80% TGA was diluted with distilled water to 10% concentration by mixing 0.5 mL of acid with 3.5 mL of water before every peel session. The peel was applied on the left leg, weekly for 6 weeks. Assessment was done at baseline and at weeks 3 and 6. Any improvement was noted by the patient and another independent dermatologist. The right leg was untreated. Any side effects during peel application and afterwards were noted. According to the patient assessment, 4/10 patients observed mild improvement, 5/10 patients had moderate improvement, and only a single patient had marked improvement. In the physician assessment, 2/10 patients had >50% improvement, 5/10 patients had 30-40% improvement, and 3/10 patients had 10-20% improvement. Side effects included slight burning during application and foul odor. A single patient had intense erythema and mild swelling of the leg after peel application. 10% TGA is effective in the partial clearance of PPD dyspigmentation with weekly sessions for 6 weeks without any serious side effects.

Stewart-Treves Syndrome in the Lower Limb after Arthroplasty- A Case Report.

Stewart-Treves Syndrome is a rare and fatal condition where cutaneous angiosarcoma-a high-grade malignant tumor originating in the vascular and lymphatic endothelium-classically develops in the upper limbs post-mastectomy, with radiation therapy and axillary lymph node dissection. There are very few reports of the syndrome developing in the lower limbs, without any preceding malignancy or radiation therapy. The median development time is 11 years. Angiosarcoma originates in the vascular and lymphatic vessels, and the diagnosis is based on histopathology and immunohistochemistry findings. We report an unusual presentation of the Stewart-Treves Syndrome in an elderly female involving the lower limb with preexisting chronic lymphedema, where the tumor developed 15 months after total knee arthroplasty.

An Unusual Case of a Dematiaceous Fungus with an Exclusive Cerebral Involvement After ABO-Incompatible Renal Transplantation.

BACKGROUND Cladophialophora carrionii was detected postoperatively in a cerebral space-occupying lesion of a patient who had undergone ABO-incompatible renal transplantation. The infection was successfully treated with oral terbinafine and itraconazole. CASE REPORT An otherwise healthy 46-year-old man underwent ABO-incompatible renal transplantation. Postoperatively, he was hemodynamically stable and the graft was functioning well. Within 2 weeks, the patient developed clinical depression, followed by seizures and left-side hemiparesis. There were no skin findings. Radiological investigation showed 2 space-occupying lesions in the brain parenchyma. The patient's condition improved after partial frontal lobectomy and microsurgical abscess evacuation, with a short course of liposomal amphotericin B and a combination of oral terbinafine and itraconazole. Microbiological examination of the pus showed growth of C. carrionii, which predominantly causes subcutaneous mycoses. CONCLUSIONS It is very rare for melanized fungal infections to cause an exclusively cerebral disease without any skin involvement. Furthermore, among established cases, C. carrionii is a very rarely detected pathogen.

Clinicomycological Study of Dermatophytosis in a Tertiary Care Hospital in Eastern India: A Cross-sectional Study.

INTRODUCTION: Dermatophytosis is a fungal infection of the skin, hair, and nails. In the past several years, it has emerged as a general public health problem in our country. Studies from different regions reveal varying patterns of etiological distribution of the disease. AIMS AND OBJECTIVES: To estimate the prevalence of different fungal species associated with dermatophytosis and to find out any possible association of the type of fungus with different clinical parameters of the disease. MATERIALS AND METHODS: This was a cross-sectional study among 311 clinically diagnosed dermatophytosis cases from a tertiary care center in eastern India. Potassium hydroxide (KOH) mount and fungal culture were done from samples of skin, hair, and nails, and various clinical parameters were analyzed. RESULTS: There was a male preponderance among cases and maximum patients belonged to third decade of life. Most common presentation was tinea corporis et cruris (39.5%). Family history was positive in 48.8% of cases. Trichophyton mentagrophytes was the most common fungal species (79.91%) grown in culture followed by Trichophyton rubrum (13.53%). Majority of patients had a mild body surface area involvement. We did not find statistically significant association of any clinical parameters with type of organism isolated. CONCLUSION: Trichophyton mentagrophytes was the most common isolated fungal species. This is in contrast to several studies where T.rubrum was the frequently found organism. There was no significant association of any clinical parameters like body surface area, number of sites, or duration of diseasewith fungal species isolated in culture.
