Atypical and Unpredictable Superficial Mycosis Presentations: A Narrative Review

While typically exhibiting characteristic features, fungal infections can sometimes present in an unusual context, having improbable localization (eyelid, face, or joint); mimicking other skin diseases such as eczema, psoriasis, or mycosis fungoides; and appearing with unexpected color, shape, or distribution. The emergence of such a challenging clinical picture is attributed to the complex interplay of host characteristics (hygiene and aging population), environment (climate change), advances in medical procedures, and agent factors (fungal resistance and species emergence). We aim to provide a better understanding of unusual epidemiological contexts and atypical manifestations of fungal superficial diseases, knowing that there is no pre-established clinical guide for these conditions. Thus, a literature examination was performed to provide a comprehensive analysis on rare and atypical superficial mycosis as well as an update on certain fungal clinical manifestations and their significance. The research and standard data extraction were performed using PubMed, Medline, Scopus, and EMBASE databases, and a total of 222 articles were identified. This review covers published research findings for the past six months.

Trichophyton rubrum Skin Folliculitis in Behçet's Disease

A 29-year-old patient with Behçet’s disease based on three major criteria (i.e., oral ulceration, genital ulceration, and eye lesion) presented with intractable pruritus associated with pinpoint red nodules involving the hair follicles of the back along with steroid-refractory local treatment. Simple light microscopic examination of a skin scraping revealed fungal contamination, and culture on Sabouraud’s medium confirmed Trichophyton rubrum as the agent of folliculitis. Behçet’s disease is characterized by recurrent attacks of acute inflammation. Although the diagnosis of sterile folliculitis-like disorder is currently retained among patients with Behçet’s disease, especially in the lower part of the body, it resembles dermatophytic folliculitis, which can be related to immunosuppressive therapy. Hence, patients with recalcitrant folliculitis predominating on the back who are receiving immunosuppressive treatment should be evaluated for fungal infection, as recognition of this disease may enable earlier diagnosis and treatment.

[Physicochemical quality of drinking water in Southern Algeria: study of excess mineral salts]

The aim of this study was to determine the physicochemical composition of water intended for human consumption in several regions of Southern Algeria. Excess minerals in drinking water, including magnesium, calcium, sulfates and fluorides play a fundamental role in the prevention of urinary calculi, which are formed mainly from calcium oxalate. The ever-increasingly prevalence of this disorder and its recurrence make it a real public health problem in Algeria. The most elementary preventive treatment, recommended to all subjects with lithiasis, is to drink 2 to 3 L water distributed throughout the (24-hour) day. This study began by conducting a physicochemical analysis of the principal components of water from several sources. We will subsequently test it to examine the effects of its mineral salts on the crystallization kinetics of the principal component of calculi (calcium oxalate). The results indicate that 77.5 % of the samples had magnesium concentrations ([Mg 2+] > 50 mg/L), 95 % were sulfated, with sulfate ion concentrations exceeding the standard recommended by WHO ([SO4 2-] > 250 mg/L). Moreover, 57.5 % had excess fluoride levels, [F-] > 1.5 mg/L, and 65 % excessive calcium concentrations, with Ca 2+ > 150 mg/L.
