Abstact: BACKGROUND: Coronavirus disease (COVID-19) currently named SARS-CoV-2 is a contagious disease caused by a coronavirus; incompatible data are present on the possible relationship among COVID-19 vaccines and hair loss.

Aims: The objective of the current study was to assess dermoscopically the prevalence of hair loss among an Egyptian population following COVID-19 vaccination.

Methods: A total of 2000 participants were enrolled in this cross-sectional study. Adult males and females who received one of recognized COVID-19 vaccine were included, irrespective of the status of previous COVID-19 infection. Those who were aged less than 18 years or above 60 years were excluded. Furthermore, subjects self-reporting hair loss were assessed by dermoscopy.

Results: Among the studied cases, n = 478 (23.9%) complained of hair loss following vaccination. The majority of cases noticed their hair loss during the first 2 months post-vaccination (n = 215 after the first month and n = 158 after the 2nd month respectively).

Conclusion: We reported prevalence of post-vaccination hair fall that was confirmed by trichoscopy and which affected approximately one quarter of participants who received COVID-19 vaccines. Other factors, such as stress and infection, cannot be excluded and remain to be further investigated by larger multicenter studies.

Purpose: To describe a technique using retroauricular scalp graft for eyebrow reconstruction, along with problems encountered and countermeasures in treatment.

Methods: We present a patient with eyebrow loss following resection of a malignant schwannoma. We initially covered the defect from the upper eyelid to the eyebrow area with artificial dermis for hemostasis and to increase the granulation of the graft bed.

The hair follicle is a complex of mesenchymal and epithelial cells acquiring different properties and characteristics responsible for fulfilling its inductive and regenerative role. The epidermal and dermal crosstalk induces morphogenesis and maintains hair follicle cycling properties. The hair follicle is enriched with pluripotent stem cells, where dermal papilla (DP) cells and dermal sheath (DS) cells constitute the dermal compartment and the epithelial stem cells existing in the bulge region exert their regenerative role by mediating the epithelial-mesenchymal interaction (EMI).

Hearing loss is highly related to acoustic injuries and mechanical damage of ear tissues. The mechanical responses of ear tissues are difficult to measure experimentally, especially cochlear hair cells within the organ of Corti (OC) at microscale. Finite element (FE) modeling has become an important tool for simulating acoustic wave transmission and studying cochlear mechanics.
