Introduction: Although the diagnosis of tinea capitis is mainly microbiological, the risk of evolution towards cicatricial alopecia in the most severe cases requires empirical treatment based on physical examination and complementary examinations.
Methods: Two patients were evaluated by physical examination, cutaneous ultrasound and microbiological examination.
Results: Ultrasound showed follicular widening and increased vascularization in Doppler mode.

A 3-year-old male sugar glider presented with pruritus and alopecia primarily affecting the back and neck regions. Dermatologic diagnostics ruled out common causes. Skin biopsies revealed cutaneous epitheliotropic T-cell lymphoma, a rare condition in sugar gliders.

Vitamin D-dependent rickets type 2A (VDDR2A) is a rare cause of infantile-onset alopecia, characterized by severe hypotrichosis, small cutaneous cysts, early-onset treatment-resistant rickets, and hypocalcemia. Alopecia, often starting a few weeks to months after birth, may be the presenting feature. We present three cases of VDDR2A with genetic variants in the vitamin D receptor (VDR) gene, their clinical features and biochemical parameters.

Silica nanoparticles-embedded smart-gels are efficient drug carrier systems due to their structural flexibility, high porosity, and ease of formulation development. Herein, the extent of interaction of minoxidil (MXD), a potent vasodilator prodrug, with silica nanoparticles (SiNPs) and alginate (ALG) was investigated. The SiNPs were prepared by extracting silica from rice husk ash, and these SiNPs were further used to prepare MXD-loaded-SiNPs (MXD-SiNPs) by loading them with an appropriate amount of MXD.
