Trichophyton erinacei is an emerging cause of dermatophyte infections, which are frequently isolated from hedgehogs. Nail infections from T. erinacei are rarely reported. We describe the case of a 23-year-old Thai female who had a history of systemic lupus erythematosus with lupus nephritis type III and who developed widespread skin and nail infections caused by T. erinacei that were most likely transmitted from a hedgehog. Although the patient did not demonstrate a clinical improvement or mycological cure following systemic itraconazole and fluconazole treatment, she achieved clinical and mycological cures after terbinafine therapy. A drug susceptibility test should be performed in patients with T. erinacei infections to facilitate decision-making about antifungal therapy. Here, we are the first to report a case of proximal subungual onychomycosis from a T. erinacei infection.

Objective: This study aimed to determine the association between the severity of inflammation at each anatomical sexual activity from gram staining with Neisseria gonorrhoeae (NG) and Chlamydia trachomatis (CT) infections. Materials & Methods: This study was conducted using laboratory test data from patients at the Bangrak Sexually Transmitted Infections Center. The data obtained consisted of gram staining, which was divided by the number of polymorphonuclear leukocytes (PMNL), NG culture, and Nucleic Acid Amplification Test (NAAT) for NG and CT results. Results: For the diagnostic association between PMNL and NG infection, the results revealed that samples with urethral PMNL 3+ or 4+ carried a significant likelihood ratio (LR) for positive infection, LR 5.61 (P<0.001) and LR 59.66 (P<0.001), respectively. Cervical, rectal, and pharyngeal PMNL was not related to infection. For CT infection, urethral gram stains with PMNL levels were greater than or equal to 2+ and cervical specimens with PMNL 4+ were associated with CT infection. Rectal and pharyngeal PMNL showed no significant association with CT infection. Conclusion: Determination of PMNL levels from gram staining contributes to the diagnosis of patients with NG and CT in the urethra, particularly for patients with a high degree of inflammation.
