  Pityrosporum folliculitis (PF) is a common skin condition that can be easily misdiagnosed, especially by non-dermatologists. […] However, there is scant literature regarding the clinical epidemiology of PF. To our knowledge, in Singapore, only one prior epidemiological study was performed in 1987. […] Through this study, we aimed to provide an update regarding the epidemiology, diagnosis and treatment of patients with PF in Singapore. […] The epidemiologic and clinical features of patients confirmed as having PF were analysed, and the significant findings are summarised in Table I. […] Most (35.0%) patients with PF in our study were aged between 21 and 30 years. […] There were 162 male and 52 female patients, yielding a male-to-female ratio of 3:1. […] The lesions predominantly occurred on the trunk and back areas, with 123 (57.5%) patients presenting with lesions on the trunk and 137 (64.0%) patients presenting with lesions on their back. […] Our findings were similar to those of a previous study conducted in 1987 on the epidemiology of PF in Singapore. […] In conclusion, our study updates the local epidemiology, diagnosis and treatment of patients with PF in Singapore.

  https://health.mil/News/Articles/2023/08/01/Pseudofolliculitis-barbae

  Pseudofolliculitis barbae, also known as razor bumps or shaving bumps, results from an inflammatory, foreign body reaction of the skin, caused by shortened and sharpened hair piercing to the epidermis and dermis.1 While PFB can affect any person who regularly shaves, literature demonstrates an increased prevalence for persons with tightly curly hair, particularly African American and Hispanic individuals, including service members in the U.S. military.1-3 Current grooming standards in the U.S. military mandate facial shaving to ensure adequate fitting and sealing of protective masks.1 A shaving waiver may be issued for medical reasons such as PFB, or for religious reasons, among others.1,4 […] […] This Surveillance Snapshot describes the frequency of PFB cases among active component service members of the U.S. military from 2000 through 2022. A PFB case was counted once per year if the ACSM demonstrated either two outpatient or theater medical data store encounters within 60 days, or one inpatient encounter within the year. Overall, the frequency of PFB cases increased over the surveillance period and varied greatly by race/ethnicity, disproportionally affecting Non-Hispanic Black service members (Figure). Non-Hispanic Blacks, who have historically comprised 16-18% of the U.S military in the past 20 years,5-7 constitute a majority (63.5%) of PFB cases. The frequency trend is well out of proportion to the change in troop strength. The increase in reported cases from 50 in 2000 to 2,404 in 2022 may warrant further study. […]

  https://www.webmd.com/skin-problems-and-treatments/what-is-folliculitis

  If your immune system is weakened, you could see another type of folliculitis on your chest and neck, as well as your arms. The bumps may clear up for a while, then come back. […] In general, you’re more likely to get the condition if you have damaged follicles. This can happen from things such as shaving, skin injuries, sticky bandages, and tight clothes. […] You also might be more likely to have folliculitis if you have an illness that affects your immune system, like diabetes, leukemia, or HIV or AIDS. […] To lower your chances of getting folliculitis, your best bet is to stop shaving for at least 3 months. […] Another way to avoid folliculitis is to limit your use of oils and other greasy skin products. These can cause blockages and trap bacteria. […] Avoid getting too close to others who have folliculitis. They may pass on their germs without realizing it.

  On 18 February 2002, the Communicable Disease Unit was notified by the local Public Health Service Laboratory of a child with a positive skin swab for Pseudomonas aeruginosa. This child had attended the local swimming pool and played on an inflatable, subsequently presenting to a Primary Care Nurse Practitioner with folliculitis. A total of 35 cases was identified during the outbreak. […] The odds ratio for developing folliculitis following use of the inflatable was 12 (95% CI 10513680). […] Nine of 10 (90%) of the inflatables sampled were colonized by P. aeruginosa. Attention should be given to the problem of routine decontamination of swimming pool inflatables.

  Pseudofolliculitis barbae, also known as razor bumps or shaving bumps, results from an inflammatory, foreign body reaction of the skin, caused by shortened and sharpened hair piercing to the epidermis and dermis.1 While PFB can affect any person who regularly shaves, literature demonstrates an increased prevalence for persons with tightly curly hair, particularly African American and Hispanic individuals, including service members in the U.S. military.1-3 Current grooming standards in the U.S. military mandate facial shaving to ensure adequate fitting and sealing of protective masks.1 A shaving waiver may be issued for medical reasons such as PFB, or for religious reasons, among others.1,4 […] […] This Surveillance Snapshot describes the frequency of PFB cases among active component service members of the U.S. military from 2000 through 2022. A PFB case was counted once per year if the ACSM demonstrated either two outpatient or theater medical data store encounters within 60 days, or one inpatient encounter within the year. Overall, the frequency of PFB cases increased over the surveillance period and varied greatly by race/ethnicity, disproportionally affecting Non-Hispanic Black service members (Figure). Non-Hispanic Blacks, who have historically comprised 16-18% of the U.S military in the past 20 years,5-7 constitute a majority (63.5%) of PFB cases. The frequency trend is well out of proportion to the change in troop strength. The increase in reported cases from 50 in 2000 to 2,404 in 2022 may warrant further study. […]

  Folliculitis is a surprisingly widespread disease of the hair. This condition can occur anywhere on the body where its hair is located, but its most common on the arms, legs, face, and back. […] Folliculitis is a fairly easy condition to spot and diagnose by a medical professional. It can be diagnosed during a regular physical examination or from an emergency appointment that you request. Diagnosis is formed based on the physical evidence and the symptoms youre experiencing. Your recent history and activities also play a role in diagnosing folliculitis since different strains can be caused by different activities. […] To prevent folliculitis, you should maintain proper hygiene and make sure any cuts on your skin are covered to prevent a bacterial infection.

[…] This present study revealed the prevalence of MF in patients clinically diagnosed with AV was 28.8%. MF can imitate and coexist with AV. Dermatologists should be aware of MF when encountering AV patients with acneiform lesions on the scalp/ hairline and upper back with pruritus. Diagnosis based on clinical presentations alone may lead to misdiagnosis. Methylene blue staining is easy to perform and beneficial to diagnose MF.

  The folliculitis market is expected to gain market growth at a potential rate of 4.90% in year 2020. Folliculitis is common and also its prevalence rate is high, which is a market driver. […] In the U.S. alone nearly 3 million cases are found annually. […] Global folliculitis market also provides you with detailed market analysis for patient analysis prognosis and cures. Prevalence, incidence, mortality, adherence rates are some of the data variables that are available in the report. Direct and indirect impact analysis of epidemiology to market growth are analysed to create a more robust and cohort multivariate statistical model for forecasting the market in the growth period.

  Nevertheless, routine monitoring still appears useful. In respect to folliculitis, detection of 102 c.f.u./ml can trigger pool closure while still allowing health authorities to credibly reassure the public that infection is unlikely. […] Our analysis and algorithms provided insights into management best practice and raised questions about the benefits of water dumping and quarantining pool socializing areas from bathers. […] Our estimates of clinical folliculitis severity as lesions/m2 were based on a small primary dataset. […] Our integration, captured in equation (1), is also a step needed for quantifying folliculitis disease burden (e.g. as disability-adjusted life years).
