Abstract
Background and Aim: Alopecia areata is an autoimmune disease of hair follicle. Osteopontin is an early T lymphocyte activator that may play a role in some immunological diseases. The aim of this study was to evaluate the serum level of osteopontin in patients with alopecia areata and compare it with the level in normal subjects.
Methods: 54 patients with alopecia areata who presented to the Razi Hospital in Tehran in 2017 and 2018 were enrolled. Half of the patients had severe disease and half of them had mild disease. Also, 52 healthy subjects were selected as control group (age and sex matched). The severity of disease was determined using SALT Score. Serum osteopontin levels were measured by ELISA method.
Results: The results showed that serum osteopontin levels were significantly higher in patients with alopecia areata than healthy subjects. There was no significant relationship between osteopontin level and SALT score or duration of the disease.
Conclusion: The level of osteopontin is higher in AA patients than normal subjects but it does not correlate with the severity of disease.

Abstract
Background and Aim: Telogen effluvium (TE) is a type of diffuse hair loss that occurs 2 to 3 months after a stressful event, including a covid-19 infection. The aim of this study was to determine the frequency of TE in women with covid-19.
Methods: This descriptive study was conducted on 270 women who referred to the skin and hair clinic of Imam Reza Ardabil Hospital with complaints of hair loss. Information related to the history of covid-19 infection, hospitalization, medications, vaccination and demographic characteristics were collected. The severity of alopecia was checked by clinical examination and traction test, and the data were analyzed with SPSS software.
Results: The average age of the patients was 41 years. 61.1% had a history of hospitalization, 43.7% used antibiotics, 61.8% used corticosteroids, and 51.8% used NSAID. The severity of Covid-19 had a significant relationship with the earlier occurrence of TE (P=0.001) and the increase in the number of pulled hairs in the traction test (P=0.001). Hospitalization due to covid-19 and corticosteroid use reduced the time between illness and onset of TE symptoms. The injection of AstraZeneca vaccine was associated with an increase in the number of plucked hairs (P=0.02).
Conclusion: The severity of TE was related to the severity of covid-19, hospitalization, corticosteroid use and injection of AstraZeneca vaccine.

Abstract
Kerion Celsi is a severe inflammatory fungal infection of the scalp that affects deeper layers of the skin. While it is uncommon in newborns, its incidence increases in children aged 3 years and older. It typically presents with swelling, spongy or boggy lesions, tenderness, hair loss (alopecia), and purulent discharge. Secondary bacterial infections are frequently seen following skin breakdown or maceration. Systemic symptoms may include enlarged lymph nodes, fever, and in very rare instances, fungal bloodstream infection (fungemia). Hypersensitivity reactions (Id reactions) can also occur. Diagnosis is guided by clinical evaluation, including patient history and physical examination, and must be confirmed using microscopy, fungal culture, and molecular diagnostic techniques. The most commonly isolated pathogens are anthropophilic Trichophyton tonsurans and zoophilic Microsporum canis. In contrast, geophilic fungi and molds are rarely implicated. Treatment is non-surgical, involving a combination of systemic and topical antifungal agents, with systemic antibiotics added when bacterial coinfection is suspected. Surgery should be avoided. Early and adequate therapy is critical to prevent permanent scarring and hair loss. The primary differential diagnosis includes bacterial infections of the skin and soft tissue.
