Lineage Tracking Dissects the Fate of Neonatal iNKT Cells Later in Life.

Invariant natural killer T (iNKT) cells in peripheral tissues are from different waves ranged from foetal, neonatal to adult ages. However, it is unclear how iNKT cells from different ages maintain in the periphery and what are their functionality. We found that in adult mice, neonate tracked-iNKT (NT-iNKT) cells are present in spleen, bone marrow, liver and lung, with a predominantly accumulation in the kidney.

Prevalence of Hidradenitis Suppurativa in Xi'an, China: A Single Center Epidemiological Study.

Background: Hidradenitis suppurativa (HS), also known as acne inversa, is a chronic, recurrent, and inflammatory disease. HS is fairly rare among the population. This study was a part of the Global Hidradenitis Suppurativa Atlas (GHiSA) initiative, aiming to establish the prevalence of HS, based on a questionnaire and subsequent clinical examination targeting healthy adults accompanying patients undergoing care in a tertiary hospital.

Rare Concurrence of Alopecia Areata in the Setting of the Lipedematous Scalp.

The lipedematous scalp (LS) is characterized by a thickened scalp because of the increased thickness of the subcutaneous fat layer. When the soft and boggy scalp is associated with shortened hairs and hair loss, it is referred to as lipedematous alopecia (LA). We report a case of alopecia areata with LS, which may be misdiagnosed as LA.

Comparison Between Trichoscopic and Histopathological Evaluations of Hair Parameters.

Background: Collecting data on hair counts helps dermatologists diagnose hair diseases more accurately. Quantitative trichoscopy analysis and pathologic examination are two common ways to evaluate hair parameters.

Purpose: The study aims to compare the effect of quantitative trichoscopy analysis and pathologic examination in hair counting and quantify the hair density of average Chinese people.
